-## Release Note
-**v1.4.0 released!** 🎆
-
-This release introduces many enhancements, improvements, and bug fixes as described below about stability, performance, data integrity, troubleshooting, and so on. Please try it and feedback. Thanks for all the contributions!
-
-- [Kubernetes 1.25 Support](https://github.com/longhorn/longhorn/issues/4003) [[doc]](https://longhorn.io/docs/1.4.0/deploy/important-notes/#pod-security-policies-disabled--pod-security-admission-introduction)
-  In the previous versions, Longhorn relies on Pod Security Policy (PSP) to authorize Longhorn components for privileged operations. From Kubernetes 1.25, PSP has been removed and replaced with Pod Security Admission (PSA). Longhorn v1.4.0 supports opt-in PSP enablement, so it can support Kubernetes versions with or without PSP.
-
-- [ARM64 GA](https://github.com/longhorn/longhorn/issues/4206)
-  ARM64 has been experimental from Longhorn v1.1.0. After receiving more user feedback and increasing testing coverage, ARM64 distribution has been stabilized with quality as per our regular regression testing, so it is qualified for general availability.
-
-- [RWX GA](https://github.com/longhorn/longhorn/issues/2293) [[lep]](https://github.com/longhorn/longhorn/blob/master/enhancements/20220727-dedicated-recovery-backend-for-rwx-volume-nfs-server.md)[[doc]](https://longhorn.io/docs/1.4.0/advanced-resources/rwx-workloads/)
-  RWX has been experimental from Longhorn v1.1.0, but it lacks availability support when the Longhorn Share Manager component behind becomes unavailable. Longhorn v1.4.0 supports NFS recovery backend based on Kubernetes built-in resource, ConfigMap, for recovering NFS client connection during the fail-over period. Also, the NFS client hard mode introduction will further avoid previous potential data loss. For the detail, please check the issue and enhancement proposal.
-
-- [Volume Snapshot Checksum](https://github.com/longhorn/longhorn/issues/4210) [[lep]](https://github.com/longhorn/longhorn/blob/master/enhancements/20220922-snapshot-checksum-and-bit-rot-detection.md)[[doc]](https://longhorn.io/docs/1.4.0/references/settings/#snapshot-data-integrity)
-  Data integrity is a continuous effort for Longhorn. In this version, Snapshot Checksum has been introduced w/ some settings to allow users to enable or disable checksum calculation with different modes.
-
-- [Volume Bit-rot Protection](https://github.com/longhorn/longhorn/issues/3198) [[lep]](https://github.com/longhorn/longhorn/blob/master/enhancements/20220922-snapshot-checksum-and-bit-rot-detection.md)[[doc]](https://longhorn.io/docs/1.4.0/references/settings/#snapshot-data-integrity)
-  When enabling the Volume Snapshot Checksum feature, Longhorn will periodically calculate and check the checksums of volume snapshots, find corrupted snapshots, then fix them.
-
-- [Volume Replica Rebuilding Speedup](https://github.com/longhorn/longhorn/issues/4783)
-  When enabling the Volume Snapshot Checksum feature, Longhorn will use the calculated snapshot checksum to avoid needless snapshot replication between nodes for improving replica rebuilding speed and resource consumption.
-
-- [Volume Trim](https://github.com/longhorn/longhorn/issues/836) [[lep]](https://github.com/longhorn/longhorn/blob/master/enhancements/20221103-filesystem-trim.md)[[doc]](https://longhorn.io/docs/1.4.0/volumes-and-nodes/trim-filesystem/#trim-the-filesystem-in-a-longhorn-volume)
-  Longhorn engine supports UNMAP SCSI command to reclaim space from the block volume.
-
-- [Online Volume Expansion](https://github.com/longhorn/longhorn/issues/1674) [[doc]](https://longhorn.io/docs/1.4.0/volumes-and-nodes/expansion)
-  Longhorn engine supports optional parameters to pass size expansion requests when updating the volume frontend to support online volume expansion and resize the filesystem via CSI node driver.
-
-- [Local Volume via Data Locality Strict Mode](https://github.com/longhorn/longhorn/issues/3957) [[lep]](https://github.com/longhorn/longhorn/blob/master/enhancements/20200819-keep-a-local-replica-to-engine.md)[[doc]](https://longhorn.io/docs/1.4.0/references/settings/#default-data-locality)
-  Local volume is based on a new Data Locality setting, Strict Local. It will allow users to create one replica volume staying in a consistent location, and the data transfer between the volume frontend and engine will be through a local socket instead of the TCP stack to improve performance and reduce resource consumption.
-
-- [Volume Recurring Job Backup Restore](https://github.com/longhorn/longhorn/issues/2227) [[lep]](https://github.com/longhorn/longhorn/blob/master/enhancements/20201002-allow-recurring-backup-detached-volumes.md)[[doc]](https://longhorn.io/docs/1.4.0/snapshots-and-backups/backup-and-restore/restore-recurring-jobs-from-a-backup/)
-  Recurring jobs binding to a volume can be backed up to the remote backup target together with the volume backup metadata. They can be restored back as well for a better operation experience.
-
-- [Volume IO Metrics](https://github.com/longhorn/longhorn/issues/2406) [[doc]](https://longhorn.io/docs/1.4.0/monitoring/metrics/#volume)
-  Longhorn enriches Volume metrics by providing real-time IO stats including IOPS, latency, and throughput of R/W IO. Users can set up a monotoning solution like Prometheus to monitor volume performance.
-
-- [Longhorn System Backup & Restore](https://github.com/longhorn/longhorn/issues/1455) [[lep]](https://github.com/longhorn/longhorn/blob/master/enhancements/20220913-longhorn-system-backup-restore.md)[[doc]](https://longhorn.io/docs/1.4.0/advanced-resources/system-backup-restore/)
-  Users can back up the longhorn system to the remote backup target. Afterward, it's able to restore back to an existing cluster in place or a new cluster for specific operational purposes.
-
-- [Support Bundle Enhancement](https://github.com/longhorn/longhorn/issues/2759) [[lep]](https://github.com/longhorn/longhorn/blob/master/enhancements/20221109-support-bundle-enhancement.md)
-  Longhorn introduces a new support bundle integration based on a general [support bundle kit](https://github.com/rancher/support-bundle-kit) solution. This can help us collect more complete troubleshooting info and simulate the cluster environment.
-
-- [Tunable Timeout between Engine and Replica](https://github.com/longhorn/longhorn/issues/4491) [[doc]](https://longhorn.io/docs/1.4.0/references/settings/#engine-to-replica-timeout)
-  In the current Longhorn versions, the default timeout between the Longhorn engine and replica is fixed without any exposed user settings. This will potentially bring some challenges for users having a low-spec infra environment. By exporting the setting configurable, it will allow users adaptively tune the stability of volume operations.
-
-## Installation
-
-> **Please ensure your Kubernetes cluster is at least v1.21 before installing Longhorn v1.4.0.**
-
-Longhorn supports 3 installation ways including Rancher App Marketplace, Kubectl, and Helm. Follow the installation instructions [here](https://longhorn.io/docs/1.4.0/deploy/install/).
-
-## Upgrade
-
-> **Please ensure your Kubernetes cluster is at least v1.21 before upgrading to Longhorn v1.4.0 from v1.3.x. Only support upgrading from 1.3.x.**
-
-Follow the upgrade instructions [here](https://longhorn.io/docs/1.4.0/deploy/upgrade/).
-
-## Deprecation & Incompatibilities
-
-- Pod Security Policy is an opt-in setting. If installing Longhorn with PSP support, need to enable it first.
-- The built-in CSI Snapshotter sidecar is upgraded to v5.0.1. The v1beta1 version of Volume Snapshot custom resource is deprecated but still supported. However, it will be removed after upgrading CSI Snapshotter to 6.1 or later versions in the future, so please start using v1 version instead before the deprecated version is removed.

CHANGELOG/CHANGELOG-1.5.0.md

@@ -1,301 +0,0 @@
-## Release Note
-### **v1.5.0 released!** 🎆
-
-Longhorn v1.5.0 is the latest version of Longhorn 1.5.
-It introduces many enhancements, improvements, and bug fixes as described below including performance, stability, maintenance, resilience, and so on. Please try it and feedback. Thanks for all the contributions!
-
-> For the definition of stable or latest release, please check [here](https://github.com/longhorn/longhorn#releases).
-
-  - [v2 Data Engine based on SPDK - Preview](https://github.com/longhorn/longhorn/issues/5751)
-    > **Please note that this is a preview feature, so should not be used in any production environment. A preview feature is disabled by default and would be changed in the following versions until it becomes general availability.**
-    
-    In addition to the existing iSCSI stack (v1) data engine, we are introducing the v2 data engine based on SPDK (Storage Performance Development Kit). This release includes the introduction of volume lifecycle management, degraded volume handling, offline replica rebuilding, block device management, and orphaned replica management. For the performance benchmark and comparison with v1, check the report [here](https://longhorn.io/docs/1.5.0/spdk/performance-benchmark/).
-
-  - [Longhorn Volume Attachment](https://github.com/longhorn/longhorn/issues/3715)
-    Introducing the new Longhorn VolumeAttachment CR, which ensures exclusive attachment and supports automatic volume attachment and detachment for various headless operations such as volume cloning, backing image export, and recurring jobs.
-
-  - [Cluster Autoscaler - GA](https://github.com/longhorn/longhorn/issues/5238)
-    Cluster Autoscaler was initially introduced as an experimental feature in v1.3. After undergoing automatic validation on different public cloud Kubernetes distributions and receiving user feedback, it has now reached general availability.
-
-  - [Instance Manager Engine & Replica Consolidation](https://github.com/longhorn/longhorn/issues/5208)
-    Previously, there were two separate instance manager pods responsible for volume engine and replica process management. However, this setup required high resource usage, especially during live upgrades. In this release, we have merged these pods into a single instance manager, reducing the initial resource requirements.
-
-  - [Volume Backup Compression Methods](https://github.com/longhorn/longhorn/issues/5189)
-    Longhorn supports different compression methods for volume backups, including lz4, gzip, or no compression. This allows users to choose the most suitable method based on their data type and usage requirements.
-
-  - [Automatic Volume Trim Recurring Job](https://github.com/longhorn/longhorn/issues/5186)
-    While volume filesystem trim was introduced in v1.4, users had to perform the operation manually. From this release, users can create a recurring job that automatically runs the trim process, improving space efficiency without requiring human intervention.
-
-  - [RWX Volume Trim](https://github.com/longhorn/longhorn/issues/5143)
-    Longhorn supports filesystem trim for RWX (Read-Write-Many) volumes, expanding the trim functionality beyond RWO (Read-Write-Once) volumes only.
-
-  - [Upgrade Path Enforcement & Downgrade Prevention](https://github.com/longhorn/longhorn/issues/5131)
-    To ensure compatibility after an upgrade, we have implemented upgrade path enforcement. This prevents unintended downgrades and ensures the system and data remain intact.
-
-  - [Backing Image Management via CSI VolumeSnapshot](https://github.com/longhorn/longhorn/issues/5005)
-    Users can now utilize the unified CSI VolumeSnapshot interface to manage Backing Images similar to volume snapshots and backups.
-
-  - [Snapshot Cleanup & Delete Recurring Job](https://github.com/longhorn/longhorn/issues/3836)
-    Introducing two new recurring job types specifically designed for snapshot cleanup and deletion. These jobs allow users to remove unnecessary snapshots for better space efficiency.
-
-  - [CIFS Backup Store](https://github.com/longhorn/longhorn/issues/3599) & [Azure Backup Store](https://github.com/longhorn/longhorn/issues/1309)
-    To enhance users' backup strategies and align with data governance policies, Longhorn now supports additional backup storage protocols, including CIFS and Azure.
-
-  - [Kubernetes Upgrade Node Drain Policy](https://github.com/longhorn/longhorn/issues/3304)  
-    The new Node Drain Policy provides flexible strategies to protect volume data during Kubernetes upgrades or node maintenance operations. This ensures the integrity and availability of your volumes.

-Longhorn is a distributed block storage system for Kubernetes. Longhorn is cloud-native storage built using Kubernetes and container primitives.
-
-Longhorn is lightweight, reliable, and powerful. You can install Longhorn on an existing Kubernetes cluster with one `kubectl apply`command or by using Helm charts. Once Longhorn is installed, it adds persistent volume support to the Kubernetes cluster.
 
 Longhorn implements distributed block storage using containers and microservices. Longhorn creates a dedicated storage controller for each block device volume and synchronously replicates the volume across multiple replicas stored on multiple nodes. The storage controller and replicas are themselves orchestrated using Kubernetes. Here are some notable features of Longhorn:
 
 1. Enterprise-grade distributed storage with no single point of failure
 2. Incremental snapshot of block storage
-3. Backup to secondary storage (NFSv4 or S3-compatible object storage) built on efficient change block detection
+3. Backup to secondary storage (NFS or S3-compatible object storage) built on efficient change block detection
 4. Recurring snapshot and backup
 5. Automated non-disruptive upgrade. You can upgrade the entire Longhorn software stack without disrupting running volumes!
 6. Intuitive GUI dashboard

-# Get Started
+# Requirements
 
-## Requirements
+1.  Docker v1.13+
+2.  Kubernetes v1.14+.
+3.  `open-iscsi` has been installed on all the nodes of the Kubernetes cluster.
+    1. For GKE, recommended Ubuntu as guest OS image since it contains open-iscsi already.
+    2. For Debian/Ubuntu, use `apt-get install open-iscsi` to install.
+    3. For RHEL/CentOS, use `yum install iscsi-initiator-utils` to install.
+4. A host filesystem supports `file extents` feature on the nodes to store the data. Currently we support:
+    1. ext4
+    2. XFS
 
-For the installation requirements, refer to the [Longhorn documentation.](https://longhorn.io/docs/latest/deploy/install/#installation-requirements)
+# Install
 
-## Installation
+## On Kubernetes clusters Managed by Rancher 2.1 or newer
 
-> **NOTE**: 
+The easiest way to install Longhorn is to deploy Longhorn from Rancher Catalog.
-> Please note that the master branch is for the upcoming feature release development. 
-> For an official release installation or upgrade, please refer to the below ways.
 
-Longhorn can be installed on a Kubernetes cluster in several ways:
+1. On Rancher UI, select the cluster and project you want to install Longhorn. We recommended to create a new project e.g. `Storage` for Longhorn.
+2. Navigate to the `Catalog Apps` screen. Select `Launch`, find Longhorn in the list. Select `View Details`, then click `Launch`. Longhorn will be installed in the `longhorn-system` namespace.
 
-- [Rancher App Marketplace](https://longhorn.io/docs/latest/deploy/install/install-with-rancher/)
+After Longhorn has been successfully installed, you can access the Longhorn UI by navigating to the `Catalog Apps` screen.
-- [kubectl](https://longhorn.io/docs/latest/deploy/install/install-with-kubectl/)
-- [Helm](https://longhorn.io/docs/latest/deploy/install/install-with-helm/)
 
-## Documentation
+One benefit of installing Longhorn through Rancher catalog is Rancher provides authentication to Longhorn UI.
 
-The official Longhorn documentation is [here.](https://longhorn.io/docs)
+If there is a new version of Longhorn available, you will see an `Upgrade Available` sign on the `Catalog Apps` screen. You can click `Upgrade` button to upgrade Longhorn manager. See more about upgrade [here](#upgrade).
 
-# Get Involved
+## On any Kubernetes cluster
 
-## Discussion, Feedback
+### Install Longhorn with kubectl
+You can install Longhorn on any Kubernetes cluster using following command:
 
-If having any discussions or feedbacks, feel free to [file a discussion](https://github.com/longhorn/longhorn/discussions).
+```
+kubectl apply -f https://raw.githubusercontent.com/longhorn/longhorn/master/deploy/longhorn.yaml
+```
+Google Kubernetes Engine (GKE) requires additional setup in order for Longhorn to function properly. If your are a GKE user, read [this page](docs/gke.md) before proceeding.
 
-## Features Request, Bug Reporting
+### Install Longhorn with Helm
+First, you need to initialize Helm locally and [install Tiller into your Kubernetes cluster with RBAC](https://helm.sh/docs/using_helm/#role-based-access-control).
 
-If having any issues, feel free to [file an issue](https://github.com/longhorn/longhorn/issues/new/choose).
+Then download Longhorn repository:
-We have a weekly community issue review meeting to review all reported issues or enhancement requests.
+```
+git clone https://github.com/longhorn/longhorn.git
+```
 
-When creating a bug issue, please help upload the support bundle to the issue or send to
+Now using following command to install Longhorn:
-[longhorn-support-bundle](mailto:longhorn-support-bundle@suse.com).
+* Helm2
+```
+helm install ./longhorn/chart --name longhorn --namespace longhorn-system
+```
+* Helm3
+```
+kubectl create namespace longhorn-system
+helm install longhorn ./longhorn/chart/ --namespace longhorn-system
+```
+---
 
-## Report Vulnerabilities
+Longhorn will be installed in the namespace `longhorn-system`
 
-If having any vulnerabilities found, please report to [longhorn-security](mailto:longhorn-security@suse.com).
+One of the two available drivers (CSI and Flexvolume) would be chosen automatically based on the version of Kubernetes you use. See [here](docs/driver.md) for details.

+kubectl create -f https://raw.githubusercontent.com/longhorn/longhorn/master/examples/storageclass.yaml
+```
+
+Now you can create a pod using Longhorn like this:
+```
+kubectl create -f https://raw.githubusercontent.com/longhorn/longhorn/master/examples/pvc.yaml
+```
+
+The above yaml file contains two parts:
+1. Create a PVC using Longhorn StorageClass.
+```
+apiVersion: v1
+kind: PersistentVolumeClaim
+metadata:
+  name: longhorn-volv-pvc
+spec:
+  accessModes:
+    - ReadWriteOnce
+  storageClassName: longhorn
+  resources:
+    requests:
+      storage: 2Gi
+```
+
+2. Use it in the a Pod as a persistent volume:
+```
+apiVersion: v1
+kind: Pod
+metadata:
+  name: volume-test
+  namespace: default
+spec:
+  containers:
+  - name: volume-test
+    image: nginx:stable-alpine
+    imagePullPolicy: IfNotPresent
+    volumeMounts:
+    - name: volv
+      mountPath: /data
+    ports:
+    - containerPort: 80
+  volumes:
+  - name: volv
+    persistentVolumeClaim:
+      claimName: longhorn-volv-pvc
+```

+
+# Uninstall Longhorn
+
+### Using kubectl
+1. To prevent damaging the Kubernetes cluster, we recommend deleting all Kubernetes workloads using Longhorn volumes (PersistentVolume, PersistentVolumeClaim, StorageClass, Deployment, StatefulSet, DaemonSet, etc) first.
+
+2. Create the uninstallation job to clean up CRDs from the system and wait for success:
+  ```
+  kubectl create -f https://raw.githubusercontent.com/longhorn/longhorn/master/uninstall/uninstall.yaml
+  kubectl get job/longhorn-uninstall -w
+  ```
+
+Example output:
+```
+$ kubectl create -f https://raw.githubusercontent.com/longhorn/longhorn/master/uninstall/uninstall.yaml
+serviceaccount/longhorn-uninstall-service-account created
+clusterrole.rbac.authorization.k8s.io/longhorn-uninstall-role created
+clusterrolebinding.rbac.authorization.k8s.io/longhorn-uninstall-bind created
+job.batch/longhorn-uninstall created
+
+$ kubectl get job/longhorn-uninstall -w
+NAME                 COMPLETIONS   DURATION   AGE
+longhorn-uninstall   0/1           3s         3s
+longhorn-uninstall   1/1           20s        20s
+^C
+```
+
+3. Remove remaining components:
+  ```
+  kubectl delete -f https://raw.githubusercontent.com/longhorn/longhorn/master/deploy/longhorn.yaml
+  kubectl delete -f https://raw.githubusercontent.com/longhorn/longhorn/master/uninstall/uninstall.yaml
+  ```
+ 
+Tip: If you try `kubectl delete -f https://raw.githubusercontent.com/longhorn/longhorn/master/deploy/longhorn.yaml` first and get stuck there, 
+pressing `Ctrl C` then running `kubectl create -f https://raw.githubusercontent.com/longhorn/longhorn/master/uninstall/uninstall.yaml` can also help you remove Longhorn. Finally, don't forget to cleanup remaining components.
+
+### Using Helm
+```
+helm delete longhorn --purge
+```

 ## Source Code
 
 Longhorn is 100% open source software. Project source code is spread across a number of repos:
 
 1. Longhorn Engine -- Core controller/replica logic https://github.com/longhorn/longhorn-engine
-2. Longhorn Instance Manager -- Controller/replica instance lifecycle management https://github.com/longhorn/longhorn-instance-manager
+2. Longhorn Manager -- Longhorn orchestration, includes CSI driver for Kubernetes https://github.com/longhorn/longhorn-manager
-3. Longhorn Share Manager -- NFS provisioner that exposes Longhorn volumes as ReadWriteMany volumes. https://github.com/longhorn/longhorn-share-manager
+3. Longhorn UI -- Dashboard https://github.com/longhorn/longhorn-ui
-4. Backing Image Manager -- Backing image file lifecycle management. https://github.com/longhorn/backing-image-manager
-5. Longhorn Manager -- Longhorn orchestration, includes CSI driver for Kubernetes https://github.com/longhorn/longhorn-manager
-6. Longhorn UI -- Dashboard https://github.com/longhorn/longhorn-ui
 
 ## Prerequisites
 
-1. A container runtime compatible with Kubernetes (Docker v1.13+, containerd v1.3.7+, etc.)
+1. Rancher v2.1+
-2. Kubernetes >= v1.21
+2. Docker v1.13+
-3. Make sure `bash`, `curl`, `findmnt`, `grep`, `awk` and `blkid` has been installed in all nodes of the Kubernetes cluster.
+3. Kubernetes v1.14+
-4. Make sure `open-iscsi` has been installed, and the `iscsid` daemon is running on all nodes of the Kubernetes cluster. For GKE, recommended Ubuntu as guest OS image since it contains `open-iscsi` already.
+4. Make sure `curl`, `findmnt`, `grep`, `awk` and `blkid` has been installed in all nodes of the Kubernetes cluster.

-## Upgrading to Kubernetes v1.25+
-
-Starting in Kubernetes v1.25, [Pod Security Policies](https://kubernetes.io/docs/concepts/security/pod-security-policy/) have been removed from the Kubernetes API.
-
-As a result, **before upgrading to Kubernetes v1.25** (or on a fresh install in a Kubernetes v1.25+ cluster), users are expected to perform an in-place upgrade of this chart with `enablePSP` set to `false` if it has been previously set to `true`.
-
-> **Note:**
-> If you upgrade your cluster to Kubernetes v1.25+ before removing PSPs via a `helm upgrade` (even if you manually clean up resources), **it will leave the Helm release in a broken state within the cluster such that further Helm operations will not work (`helm uninstall`, `helm upgrade`, etc.).**
->
-> If your charts get stuck in this state, you may have to clean up your Helm release secrets.
-Upon setting `enablePSP` to false, the chart will remove any PSP resources deployed on its behalf from the cluster. This is the default setting for this chart.
-
-As a replacement for PSPs, [Pod Security Admission](https://kubernetes.io/docs/concepts/security/pod-security-admission/) should be used. Please consult the Longhorn docs for more details on how to configure your chart release namespaces to work with the new Pod Security Admission and apply Pod Security Standards.
-
-## Installation
-1. Add Longhorn chart repository.
-```
-helm repo add longhorn https://charts.longhorn.io
-```
-
-2. Update local Longhorn chart information from chart repository.
-```
-helm repo update
-```
-
-3. Install Longhorn chart.
-- With Helm 2, the following command will create the `longhorn-system` namespace and install the Longhorn chart together.
-```
-helm install longhorn/longhorn --name longhorn --namespace longhorn-system
-```
-- With Helm 3, the following commands will create the `longhorn-system` namespace first, then install the Longhorn chart.
-
-```
-kubectl create namespace longhorn-system
-helm install longhorn longhorn/longhorn --namespace longhorn-system
-```
 
 ## Uninstallation
 
-With Helm 2 to uninstall Longhorn.
+1. To prevent damage to the Kubernetes cluster, we recommend deleting all Kubernetes workloads using Longhorn volumes (PersistentVolume, PersistentVolumeClaim, StorageClass, Deployment, StatefulSet, DaemonSet, etc).
+
+2. From Rancher UI, navigate to `Catalog Apps` tab and delete Longhorn app.
+
+## Troubleshooting
+
+### I deleted the Longhorn App from Rancher UI instead of following the uninstallation procedure
+
+Redeploy the (same version) Longhorn App. Follow the uninstallation procedure above.
+
+### Problems with CRDs
+
+If your CRD instances or the CRDs themselves can't be deleted for whatever reason, run the commands below to clean up. Caution: this will wipe all Longhorn state!
+
 ```
-kubectl -n longhorn-system patch -p '{"value": "true"}' --type=merge lhs deleting-confirmation-flag
+# Delete CRD instances and definitions
-helm delete longhorn --purge
+curl -s https://raw.githubusercontent.com/longhorn/longhorn-manager/master/hack/cleancrds.sh |bash -s v062
+curl -s https://raw.githubusercontent.com/longhorn/longhorn-manager/master/hack/cleancrds.sh |bash -s v070
 ```
 
-With Helm 3 to uninstall Longhorn.
-```
-kubectl -n longhorn-system patch -p '{"value": "true"}' --type=merge lhs deleting-confirmation-flag
-helm uninstall longhorn -n longhorn-system
-kubectl delete namespace longhorn-system
-```

-
-| Key | Description |
-|-----|-------------|
-| defaultSettings.allowEmptyDiskSelectorVolume | Allow Scheduling Empty Disk Selector Volumes To Any Disk |
-| defaultSettings.allowEmptyNodeSelectorVolume | Allow Scheduling Empty Node Selector Volumes To Any Node |
-| defaultSettings.allowRecurringJobWhileVolumeDetached | If this setting is enabled, Longhorn will automatically attaches the volume and takes snapshot/backup  when it is the time to do recurring snapshot/backup. |
-| defaultSettings.allowVolumeCreationWithDegradedAvailability | This setting allows user to create and attach a volume that doesn't have all the replicas scheduled at the time of creation. |
-| defaultSettings.autoCleanupSystemGeneratedSnapshot | This setting enables Longhorn to automatically cleanup the system generated snapshot after replica rebuild is done. |
-| defaultSettings.autoDeletePodWhenVolumeDetachedUnexpectedly | If enabled, Longhorn will automatically delete the workload pod that is managed by a controller (e.g. deployment, statefulset, daemonset, etc...)  when Longhorn volume is detached unexpectedly (e.g. during Kubernetes upgrade, Docker reboot, or network disconnect). By deleting the pod, its controller restarts the pod and Kubernetes handles volume reattachment and remount. |
-| defaultSettings.autoSalvage | If enabled, volumes will be automatically salvaged when all the replicas become faulty e.g. due to network disconnection. Longhorn will try to figure out which replica(s) are usable, then use them for the volume. By default true. |
-| defaultSettings.backingImageCleanupWaitInterval | This interval in minutes determines how long Longhorn will wait before cleaning up the backing image file when there is no replica in the disk using it. |
-| defaultSettings.backingImageRecoveryWaitInterval | This interval in seconds determines how long Longhorn will wait before re-downloading the backing image file when all disk files of this backing image become failed or unknown. |
-| defaultSettings.backupCompressionMethod | This setting allows users to specify backup compression method. |
-| defaultSettings.backupConcurrentLimit | This setting controls how many worker threads per backup concurrently. |
-| defaultSettings.backupTarget | The endpoint used to access the backupstore. Available: NFS, CIFS, AWS, GCP, AZURE. |
-| defaultSettings.backupTargetCredentialSecret | The name of the Kubernetes secret associated with the backup target. |
-| defaultSettings.backupstorePollInterval | In seconds. The backupstore poll interval determines how often Longhorn checks the backupstore for new backups. Set to 0 to disable the polling. By default 300. |
-| defaultSettings.concurrentAutomaticEngineUpgradePerNodeLimit | This setting controls how Longhorn automatically upgrades volumes' engines to the new default engine image after upgrading Longhorn manager. The value of this setting specifies the maximum number of engines per node that are allowed to upgrade to the default engine image at the same time. If the value is 0, Longhorn will not automatically upgrade volumes' engines to default version. |
-| defaultSettings.concurrentReplicaRebuildPerNodeLimit | This setting controls how many replicas on a node can be rebuilt simultaneously. |
-| defaultSettings.concurrentVolumeBackupRestorePerNodeLimit | This setting controls how many volumes on a node can restore the backup concurrently. Set the value to **0** to disable backup restore. |
-| defaultSettings.createDefaultDiskLabeledNodes | Create default Disk automatically only on Nodes with the label "node.longhorn.io/create-default-disk=true" if no other disks exist. If disabled, the default disk will be created on all new nodes when each node is first added. |
-| defaultSettings.defaultDataLocality | Longhorn volume has data locality if there is a local replica of the volume on the same node as the pod which is using the volume. |
-| defaultSettings.defaultDataPath | Default path to use for storing data on a host. By default "/var/lib/longhorn/" |
-| defaultSettings.defaultLonghornStaticStorageClass | The 'storageClassName' is given to PVs and PVCs that are created for an existing Longhorn volume. The StorageClass name can also be used as a label, so it is possible to use a Longhorn StorageClass to bind a workload to an existing PV without creating a Kubernetes StorageClass object. By default 'longhorn-static'. |
-| defaultSettings.defaultReplicaCount | The default number of replicas when a volume is created from the Longhorn UI. For Kubernetes configuration, update the `numberOfReplicas` in the StorageClass. By default 3. |
-| defaultSettings.deletingConfirmationFlag | This flag is designed to prevent Longhorn from being accidentally uninstalled which will lead to data lost. |
-| defaultSettings.disableRevisionCounter | This setting is only for volumes created by UI. By default, this is false meaning there will be a reivision counter file to track every write to the volume. During salvage recovering Longhorn will pick the replica with largest reivision counter as candidate to recover the whole volume. If revision counter is disabled, Longhorn will not track every write to the volume. During the salvage recovering, Longhorn will use the 'volume-head-xxx.img' file last modification time and file size to pick the replica candidate to recover the whole volume. |
-| defaultSettings.disableSchedulingOnCordonedNode | Disable Longhorn manager to schedule replica on Kubernetes cordoned node. By default true. |
-| defaultSettings.engineReplicaTimeout | In seconds. The setting specifies the timeout between the engine and replica(s), and the value should be between 8 to 30 seconds. The default value is 8 seconds. |
-| defaultSettings.failedBackupTTL | In minutes. This setting determines how long Longhorn will keep the backup resource that was failed. Set to 0 to disable the auto-deletion. |
-| defaultSettings.fastReplicaRebuildEnabled | This feature supports the fast replica rebuilding. It relies on the checksum of snapshot disk files, so setting the snapshot-data-integrity to **enable** or **fast-check** is a prerequisite. |
-| defaultSettings.guaranteedInstanceManagerCPU | This integer value indicates how many percentage of the total allocatable CPU on each node will be reserved for each instance manager Pod. You can leave it with the default value, which is 12%. |
-| defaultSettings.kubernetesClusterAutoscalerEnabled | Enabling this setting will notify Longhorn that the cluster is using Kubernetes Cluster Autoscaler. |
-| defaultSettings.logLevel | The log level Panic, Fatal, Error, Warn, Info, Debug, Trace used in longhorn manager. Default to Info. |
-| defaultSettings.nodeDownPodDeletionPolicy | Defines the Longhorn action when a Volume is stuck with a StatefulSet/Deployment Pod on a node that is down. |
-| defaultSettings.nodeDrainPolicy | Define the policy to use when a node with the last healthy replica of a volume is drained. |
-| defaultSettings.offlineReplicaRebuilding | This setting allows users to enable the offline replica rebuilding for volumes using v2 data engine. |
-| defaultSettings.orphanAutoDeletion | This setting allows Longhorn to delete the orphan resource and its corresponding orphaned data automatically like stale replicas. Orphan resources on down or unknown nodes will not be cleaned up automatically. |
-| defaultSettings.priorityClass | priorityClass for longhorn system componentss |
-| defaultSettings.recurringFailedJobsHistoryLimit | This setting specifies how many failed backup or snapshot job histories should be retained. History will not be retained if the value is 0. |
-| defaultSettings.recurringSuccessfulJobsHistoryLimit | This setting specifies how many successful backup or snapshot job histories should be retained. History will not be retained if the value is 0. |
-| defaultSettings.removeSnapshotsDuringFilesystemTrim | This setting allows Longhorn filesystem trim feature to automatically mark the latest snapshot and its ancestors as removed and stops at the snapshot containing multiple children. |
-| defaultSettings.replicaAutoBalance | Enable this setting automatically rebalances replicas when discovered an available node. |
-| defaultSettings.replicaDiskSoftAntiAffinity | Allow scheduling on disks with existing healthy replicas of the same volume. By default true. |
-| defaultSettings.replicaFileSyncHttpClientTimeout | In seconds. The setting specifies the HTTP client timeout to the file sync server. |
-| defaultSettings.replicaReplenishmentWaitInterval | In seconds. The interval determines how long Longhorn will wait at least in order to reuse the existing data on a failed replica rather than directly creating a new replica for a degraded volume. |
-| defaultSettings.replicaSoftAntiAffinity | Allow scheduling on nodes with existing healthy replicas of the same volume. By default false. |
-| defaultSettings.replicaZoneSoftAntiAffinity | Allow scheduling new Replicas of Volume to the Nodes in the same Zone as existing healthy Replicas. Nodes don't belong to any Zone will be treated as in the same Zone. Notice that Longhorn relies on label `topology.kubernetes.io/zone=<Zone name of the node>` in the Kubernetes node object to identify the zone. By default true. |
-| defaultSettings.restoreConcurrentLimit | This setting controls how many worker threads per restore concurrently. |
-| defaultSettings.restoreVolumeRecurringJobs | Restore recurring jobs from the backup volume on the backup target and create recurring jobs if not exist during a backup restoration. |
-| defaultSettings.snapshotDataIntegrity | This setting allows users to enable or disable snapshot hashing and data integrity checking. |
-| defaultSettings.snapshotDataIntegrityCronjob | Unix-cron string format. The setting specifies when Longhorn checks the data integrity of snapshot disk files. |
-| defaultSettings.snapshotDataIntegrityImmediateCheckAfterSnapshotCreation | Hashing snapshot disk files impacts the performance of the system. The immediate snapshot hashing and checking can be disabled to minimize the impact after creating a snapshot. |
-| defaultSettings.storageMinimalAvailablePercentage | If the minimum available disk capacity exceeds the actual percentage of available disk capacity, the disk becomes unschedulable until more space is freed up. By default 25. |
-| defaultSettings.storageNetwork | Longhorn uses the storage network for in-cluster data traffic. Leave this blank to use the Kubernetes cluster network. |
-| defaultSettings.storageOverProvisioningPercentage | The over-provisioning percentage defines how much storage can be allocated relative to the hard drive's capacity. By default 200. |
-| defaultSettings.storageReservedPercentageForDefaultDisk | The reserved percentage specifies the percentage of disk space that will not be allocated to the default disk on each new Longhorn node. |
-| defaultSettings.supportBundleFailedHistoryLimit | This setting specifies how many failed support bundles can exist in the cluster. Set this value to **0** to have Longhorn automatically purge all failed support bundles. |
-| defaultSettings.systemManagedComponentsNodeSelector | nodeSelector for longhorn system components |
-| defaultSettings.systemManagedPodsImagePullPolicy | This setting defines the Image Pull Policy of Longhorn system managed pod. e.g. instance manager, engine image, CSI driver, etc. The new Image Pull Policy will only apply after the system managed pods restart. |
-| defaultSettings.taintToleration | taintToleration for longhorn system components |
-| defaultSettings.upgradeChecker | Upgrade Checker will check for new Longhorn version periodically. When there is a new version available, a notification will appear in the UI. By default true. |
-| defaultSettings.v2DataEngine | This allows users to activate v2 data engine based on SPDK. Currently, it is in the preview phase and should not be utilized in a production environment. |

-# Longhorn Chart
-
-> **Important**: Please install the Longhorn chart in the `longhorn-system` namespace only.
-
-> **Warning**: Longhorn doesn't support downgrading from a higher version to a lower version.
-
-## Source Code
-
-Longhorn is 100% open source software. Project source code is spread across a number of repos:
-
-1. Longhorn Engine -- Core controller/replica logic https://github.com/longhorn/longhorn-engine
-2. Longhorn Instance Manager -- Controller/replica instance lifecycle management https://github.com/longhorn/longhorn-instance-manager
-3. Longhorn Share Manager -- NFS provisioner that exposes Longhorn volumes as ReadWriteMany volumes. https://github.com/longhorn/longhorn-share-manager
-4. Backing Image Manager -- Backing image file lifecycle management. https://github.com/longhorn/backing-image-manager
-5. Longhorn Manager -- Longhorn orchestration, includes CSI driver for Kubernetes https://github.com/longhorn/longhorn-manager
-6. Longhorn UI -- Dashboard https://github.com/longhorn/longhorn-ui
-
-## Prerequisites
-
-1. A container runtime compatible with Kubernetes (Docker v1.13+, containerd v1.3.7+, etc.)
-2. Kubernetes >= v1.21
-3. Make sure `bash`, `curl`, `findmnt`, `grep`, `awk` and `blkid` has been installed in all nodes of the Kubernetes cluster.
-4. Make sure `open-iscsi` has been installed, and the `iscsid` daemon is running on all nodes of the Kubernetes cluster. For GKE, recommended Ubuntu as guest OS image since it contains `open-iscsi` already.
-
-## Upgrading to Kubernetes v1.25+
-
-Starting in Kubernetes v1.25, [Pod Security Policies](https://kubernetes.io/docs/concepts/security/pod-security-policy/) have been removed from the Kubernetes API.
-
-As a result, **before upgrading to Kubernetes v1.25** (or on a fresh install in a Kubernetes v1.25+ cluster), users are expected to perform an in-place upgrade of this chart with `enablePSP` set to `false` if it has been previously set to `true`.
-
-> **Note:**
-> If you upgrade your cluster to Kubernetes v1.25+ before removing PSPs via a `helm upgrade` (even if you manually clean up resources), **it will leave the Helm release in a broken state within the cluster such that further Helm operations will not work (`helm uninstall`, `helm upgrade`, etc.).**
->
-> If your charts get stuck in this state, you may have to clean up your Helm release secrets.
-Upon setting `enablePSP` to false, the chart will remove any PSP resources deployed on its behalf from the cluster. This is the default setting for this chart.
-
-As a replacement for PSPs, [Pod Security Admission](https://kubernetes.io/docs/concepts/security/pod-security-admission/) should be used. Please consult the Longhorn docs for more details on how to configure your chart release namespaces to work with the new Pod Security Admission and apply Pod Security Standards.
-
-## Installation
-1. Add Longhorn chart repository.
-```
-helm repo add longhorn https://charts.longhorn.io
-```
-
-2. Update local Longhorn chart information from chart repository.
-```
-helm repo update
-```
-
-3. Install Longhorn chart.
-- With Helm 2, the following command will create the `longhorn-system` namespace and install the Longhorn chart together.
-```
-helm install longhorn/longhorn --name longhorn --namespace longhorn-system
-```
-- With Helm 3, the following commands will create the `longhorn-system` namespace first, then install the Longhorn chart.
-
-```
-kubectl create namespace longhorn-system
-helm install longhorn longhorn/longhorn --namespace longhorn-system
-```
-
-## Uninstallation
-
-With Helm 2 to uninstall Longhorn.
-```
-kubectl -n longhorn-system patch -p '{"value": "true"}' --type=merge lhs deleting-confirmation-flag
-helm delete longhorn --purge
-```
-
-With Helm 3 to uninstall Longhorn.
-```
-kubectl -n longhorn-system patch -p '{"value": "true"}' --type=merge lhs deleting-confirmation-flag
-helm uninstall longhorn -n longhorn-system
-kubectl delete namespace longhorn-system

-## Notes
-
-Main changes and tasks for OCP are:
-
-- On OCP / OKD, the Operating System is Managed by the Cluster
-- OCP Imposes [Security Context Constraints](https://docs.openshift.com/container-platform/4.11/authentication/managing-security-context-constraints.html)
-  - This requires everything to run with the least privilege possible. For the moment every component has been given access to run as higher privilege.
-  - Something to circle back on is network polices and which components can have their privileges reduced without impacting functionality.
-    - The UI probably can be for example.
-- openshift/oauth-proxy for authentication to the Longhorn Ui
-  - **⚠️** Currently Scoped to Authenticated Users that can delete a longhorn settings object.
-    - **⚠️** Since the UI it self is not protected, network policies will need to be created to prevent namespace <--> namespace communication against the pod or service object directly.
-    - Anyone with access to the UI Deployment can remove the route restriction. (Namespace Scoped Admin)
-- Option to use separate disk in /var/mnt/longhorn & MachineConfig file to mount /var/mnt/longhorn
-- Adding finalizers for mount propagation

-> ⚠️ Note: If you add New Nodes After the below Machine Config is applied, you will need to also reboot the node.
-
-#### Mounting Disk On Boot
-
-The Secondary Drive needs to be mounted on every boot. Save the Concents and Apply the MachineConfig with `oc apply -f`:
-
-> ⚠️ This will trigger an machine config profile update and reboot all worker nodes on the cluster

-#### Label and Annotate Nodes
-
-Label and annotate storage nodes like this:
-
-```bash
-oc get nodes --no-headers | awk '{print $1}'
-
-export NODE="worker-0"
-oc annotate node ${NODE} --overwrite node.longhorn.io/default-disks-config='[{"path":"/var/mnt/longhorn","allowScheduling":true}]'
-oc label node ${NODE} node.longhorn.io/create-default-disk=config
-```

-## Overview
-scale-test is a collection of developer scripts that are used for scaling a cluster to a certain amount of volumes
-while monitoring the time required to complete these actions.
-`sample.sh` can be used to quickly see how long it takes for the requested amount of volumes to be up and usable.
-`scale-test.py` can be used to create the amount of requested statefulsets based on the `statefulset.yaml` template,
-as well as retrieve detailed timing information per volume.
-
-
-### scale-test.py
-scale-test.py watches `pod`, `pvc`, `va` events (ADDED, MODIFIED, DELETED).
-Based on that information we can calculate the time of actions for each individual pod.
-
-In additional scale-test.py can also be used to create a set of statefulset deployment files.
-based on the `statefulset.yaml` with the following VARIABLES substituted based on the current sts index.
-`@NODE_NAME@` - schedule each sts on a dedicated node
-`@STS_NAME@` - also used for the volume-name
-
-make sure to set the correct CONSTANT values in scale-test.py before running.
-
-
-### sample.sh
-sample.sh can be used to scale to a requested amount of volumes based on the existing statefulsets 
-and node count for the current cluster.
-
-One can pass the requested amount of volumes as well as the node count of the current cluster.
-example for 1000 volumes and 100 nodes: `./sample.sh 1000 100` 
-this expects there to be a statefulset deployment for each node.

+# Rancher Longhorn Chart
+
+The following document pertains to running Longhorn from the Rancher 2.0 chart.
+
+## Source Code
+
+Longhorn is 100% open source software. Project source code is spread across a number of repos:
+
+1. Longhorn Engine -- Core controller/replica logic https://github.com/rancher/longhorn-engine
+2. Longhorn Manager -- Longhorn orchestration, includes Flexvolume driver for Kubernetes https://github.com/rancher/longhorn-manager
+3. Longhorn UI -- Dashboard https://github.com/rancher/longhorn-ui
+
+## Prerequisites
+
+1. Rancher v2.1+
+2. Docker v1.13+
+3. Kubernetes v1.8+ cluster with 1 or more nodes and Mount Propagation feature enabled. If your Kubernetes cluster was provisioned by Rancher v2.0.7+ or later, MountPropagation feature is enabled by default. [Check your Kubernetes environment now](https://github.com/rancher/longhorn#environment-check-script). If MountPropagation is disabled, the Kubernetes Flexvolume driver will be deployed instead of the default CSI driver. Base Image feature will also be disabled if MountPropagation is disabled.
+4. Make sure `curl`, `findmnt`, `grep`, `awk` and `blkid` has been installed in all nodes of the Kubernetes cluster.
+5. Make sure `open-iscsi` has been installed in all nodes of the Kubernetes cluster. For GKE, recommended Ubuntu as guest OS image since it contains `open-iscsi` already.
+
+## Uninstallation
+
+1. To prevent damage to the Kubernetes cluster, we recommend deleting all Kubernetes workloads using Longhorn volumes (PersistentVolume, PersistentVolumeClaim, StorageClass, Deployment, StatefulSet, DaemonSet, etc).
+
+2. From Rancher UI, navigate to `Catalog Apps` tab and delete Longhorn app.
+
+## Troubleshooting
+
+### I deleted the Longhorn App from Rancher UI instead of following the uninstallation procedure
+
+Redeploy the (same version) Longhorn App. Follow the uninstallation procedure above.
+
+### Problems with CRDs
+
+If your CRD instances or the CRDs themselves can't be deleted for whatever reason, run the commands below to clean up. Caution: this will wipe all Longhorn state!
+
+```
+# Delete CRD finalizers, instances and definitions
+for crd in $(kubectl get crd -o jsonpath={.items[*].metadata.name} | tr ' ' '\n' | grep longhorn.rancher.io); do
+  kubectl -n ${NAMESPACE} get $crd -o yaml | sed "s/\- longhorn.rancher.io//g" | kubectl apply -f -
+  kubectl -n ${NAMESPACE} delete $crd --all
+  kubectl delete crd/$crd
+done
+```
+
+### Volume can be attached/detached from UI, but Kubernetes Pod/StatefulSet etc cannot use it
+
+Check if volume plugin directory has been set correctly. This is automatically detected unless user explicitly set it.
+
+By default, Kubernetes uses `/usr/libexec/kubernetes/kubelet-plugins/volume/exec/`, as stated in the [official document](https://github.com/kubernetes/community/blob/master/contributors/devel/flexvolume.md#prerequisites).
+
+Some vendors choose to change the directory for various reasons. For example, GKE uses `/home/kubernetes/flexvolume` instead.
+
+User can find the correct directory by running `ps aux|grep kubelet` on the host and check the `--volume-plugin-dir` parameter. If there is none, the default `/usr/libexec/kubernetes/kubelet-plugins/volume/exec/` will be used.

+# Longhorn CSI on K3S
+
+## Requirements
+  1. Kubernetes v1.11 or higher.
+  2. Longhorn v0.4.1 or higher.
+
+
+## Instruction
+#### K3S: 
+  ##### 1. For Longhorn v0.7.0 and above
+  Longhorn v0.7.0 and above support k3s v0.10.0 and above only by default. 
+  
+  If you want to deploy these new Longhorn versions on versions before k3s v0.10.0, you need to set `--kubelet-root-dir` to `<data-dir>/agent/kubelet` for the Deployment `longhorn-driver-deployer` in `longhorn/deploy/longhorn.yaml`. 
+  `data-dir` is a `k3s` arg and it can be set when you launch a k3s server. By default it is `/var/lib/rancher/k3s`.
+  
+  ##### 2. For Longhorn before v0.7.0
+  Longhorn versions before v0.7.0 support k3s below v0.10.0 only by default. 
+  
+  If you want to deploy these older Longhorn versions on k3s v0.10.0 and above, you need to set `--kubelet-root-dir` to `/var/lib/kubelet` for the Deployment `longhorn-driver-deployer` in `longhorn/deploy/longhorn.yaml`
+
+## Troubleshooting
+### Common issues
+#### Failed to get arg root-dir: Cannot get kubelet root dir, no related proc for root-dir detection ...
+
+This error is due to Longhorn cannot detect where is the root dir setup for Kubelet, so the CSI plugin installation failed.
+
+User can override the root-dir detection by manually setting argument `kubelet-root-dir` here: 
+https://github.com/rancher/longhorn/blob/master/deploy/longhorn.yaml#L329
+
+**For K3S v0.10.0-**
+
+Run `ps aux | grep k3s` and get argument `--data-dir` or `-d` on k3s server node.
+
+e.g.
+```
+$ ps uax | grep k3s
+root      4160  0.0  0.0  51420  3948 pts/0    S+   00:55   0:00 sudo /usr/local/bin/k3s server --data-dir /opt/test/k3s/data/dir
+root      4161 49.0  4.0 259204 164292 pts/0   Sl+  00:55   0:04 /usr/local/bin/k3s server --data-dir /opt/test/k3s/data/dir
+``` 
+You will find `data-dir` in the cmdline of proc `k3s`. By default it is not set and `/var/lib/rancher/k3s` will be used. Then joining `data-dir` with `/agent/kubelet` you will get the `root-dir`. So the default `root-dir` for K3S is `/var/lib/rancher/k3s/agent/kubelet`.
+
+If K3S is using a configuration file, you would need to check the configuration file to locate the `data-dir` parameter.
+
+**For K3S v0.10.0+**
+
+It is always `/var/lib/kubelet`
+
+## Background 
+#### Longhorn versions before v0.7.0 don't work on K3S v0.10.0 or above
+K3S now sets its kubelet directory to `/var/lib/kubelet`. See [the K3S release comment](https://github.com/rancher/k3s/releases/tag/v0.10.0) for details.

+# Customized Default Setting
+
+## Overview
+During Longhorn system deployment, users can customize the default settings for Longhorn. e.g. specify `Create Default Disk With Node Labeled` and `Default Data Path` before starting the Longhorn system.
+
+## Usage
+### Note:
+1. This default setting is only for Longhorn system that hasn't been deployed. And it has no impact on the existing Longhorn system.
+2. The users should modify the settings for an existing Longhorn system via UI. 
+
+### Via Rancher UI
+[Cluster] -> System -> Apps -> Launch -> longhorn -> LONGHORN DEFAULT SETTINGS
+
+
+### Via Longhorn deployment yaml file
+1. Download the longhorn repo:
+```
+git clone https://github.com/longhorn/longhorn.git
+```
+
+2. Modify the config map named `longhorn-default-setting` in the yaml file `longhorn/deploy/longhorn.yaml`. For example:
+```
+---
+apiVersion: v1
+kind: ConfigMap
+metadata:
+  name: longhorn-default-setting
+  namespace: longhorn-system
+data:
+  default-setting.yaml: |-
+    backup-target: s3://backupbucket@us-east-1/backupstore
+    backup-target-credential-secret: minio-secret 
+    create-default-disk-labeled-nodes: true
+    default-data-path: /var/lib/rancher/longhorn-example/
+    replica-soft-anti-affinity: false
+    storage-over-provisioning-percentage: 600
+    storage-minimal-available-percentage: 15
+    upgrade-checker: false
+    default-replica-count: 2
+    guaranteed-engine-cpu:
+    default-longhorn-static-storage-class: longhorn-static-example
+    backupstore-poll-interval: 500
+    taint-toleration: key1=value1:NoSchedule; key2:NoExecute
+---
+```
+
+### Via helm
+1. Download the chart in the longhorn repo:
+```
+git clone https://github.com/longhorn/longhorn.git
+```
+
+2.1. Use helm command with `--set` flag to modify the default settings. 
+For example:
+```
+helm install ./longhorn/chart --name longhorn --namespace longhorn-system --set defaultSettings.taintToleration="key1=value1:NoSchedule; key2:NoExecute"
+```
+
+2.2. Or directly modifying the default settings in the yaml file `longhorn/chart/values.yaml` then using helm command without `--set` to deploy Longhorn. 
+For example:
+
+In `longhorn/chart/values.yaml`:
+```
+defaultSettings:
+  backupTarget: s3://backupbucket@us-east-1/backupstore
+  backupTargetCredentialSecret: minio-secret 
+  createDefaultDiskLabeledNodes: true
+  defaultDataPath: /var/lib/rancher/longhorn-example/
+  replicaSoftAntiAffinity: false
+  storageOverProvisioningPercentage: 600
+  storageMinimalAvailablePercentage: 15
+  upgradeChecker: false
+  defaultReplicaCount: 2
+  guaranteedEngineCPU:
+  defaultLonghornStaticStorageClass: longhorn-static-example
+  backupstorePollInterval: 500
+  taintToleration: key1=value1:NoSchedule; key2:NoExecute
+```
+
+Then use helm command:
+```
+helm install ./longhorn/chart --name longhorn --namespace longhorn-system
+```
+
+For more info about using helm, see:

+# Disaster Recovery Volume
+## What is Disaster Recovery Volume?
+To increase the resiliency of the volume, Longhorn supports disaster recovery volume.
+ 
+The disaster recovery volume is designed for the backup cluster in the case of the whole main cluster goes down. 
+A disaster recovery volume is normally in standby mode. User would need to activate it before using it as a normal volume.
+A disaster recovery volume can be created from a volume's backup in the backup store. And Longhorn will monitor its 
+original backup volume and incrementally restore from the latest backup. Once the original volume in the main cluster goes
+down and users decide to activate the disaster recovery volume in the backup cluster, the disaster recovery volume can be
+activated immediately in the most condition, so it will greatly reduced the time needed to restore the data from the
+backup store to the volume in the backup cluster.
+
+## How to create Disaster Recovery Volume?
+1. In the cluster A, make sure the original volume X has backup created or recurring backup scheduling.
+2. Set backup target in cluster B to be same as cluster A's.
+3. In backup page of cluster B, choose the backup volume X then create disaster recovery volume Y. It's highly recommended
+to use backup volume name as disaster volume name.
+4. Attach the disaster recovery volume Y to any node. Then Longhorn will automatically polling for the last backup of the
+volume X, and incrementally restore it to the volume Y.
+5. If volume X is down, users can activate volume Y immediately. Once activated, volume Y will become a 
+normal Longhorn volume.
+    5.1. Notice that deactivate a normal volume is not allowed.
+
+## About Activating Disaster Recovery Volume
+1. A disaster recovery volume doesn't support creating/deleting/reverting snapshot, creating backup, creating
+PV/PVC. Users cannot update `Backup Target` in Settings if any disaster recovery volumes exist.
+
+2. When users try to activate a disaster recovery volume, Longhorn will check the last backup of the original volume. If
+it hasn't been restored, the restoration will be started, and the activate action will fail. Users need to wait for 
+the restoration to complete before retrying.
+
+3. For disaster recovery volume, `Last Backup` indicates the most recent backup of its original backup volume. If the icon 
+representing disaster volume is gray, it means the volume is restoring `Last Backup` and users cannot activate this 
+volume right now; if the icon is blue, it means the volume has restored the `Last Backup`. 
+
+## RPO and RTO
+Typically incremental restoration is triggered by the periodic backup store update. Users can set backup store update 
+interval in `Setting - General - Backupstore Poll Interval`. Notice that this interval can potentially impact 
+Recovery Time Objective(RTO). If it is too long, there may be a large amount of data for the disaster recovery volume to 
+restore, which will take a long time. As for Recovery Point Objective(RPO), it is determined by recurring backup 
+scheduling of the backup volume. You can check [here](snapshot-backup.md) to see how to set recurring backup in Longhorn.
+
+e.g.:
+
+If recurring backup scheduling for normal volume A is creating backup every hour, then RPO is 1 hour.
+
+Assuming the volume creates backup every hour, and incrementally restoring data of one backup takes 5 minutes.  
+
+If `Backupstore Poll Interval` is 30 minutes, then there will be at most one backup worth of data since last restoration.
+The time for restoring one backup is 5 minute, so RTO is 5 minutes.
+
+If `Backupstore Poll Interval` is 12 hours, then there will be at most 12 backups worth of data since last restoration.
+The time for restoring the backups is 5 * 12 = 60 minutes, so RTO is 60 minutes.

+# Kubernetes driver
+
+## Background
+
+Longhorn can be used in Kubernetes to provide persistent storage through either Longhorn Container Storage Interface (CSI) driver or Longhorn FlexVolume driver. Longhorn will automatically deploy one of the drivers, depending on the Kubernetes cluster configuration. User can also specify the driver in the deployment yaml file. CSI is preferred.
+
+Noted that the volume created and used through one driver won't be recongized by Kubernetes using the other driver. So please don't switch driver (e.g. during upgrade) if you have existing volumes created using the old driver. If you really want to switch driver, see [here](upgrade.md#migrating-between-flexvolume-and-csi-driver) for instructions.
+
+## CSI
+
+### Requirement for the CSI driver
+
+1. Kubernetes v1.10+
+   1. CSI is in beta release for this version of Kubernetes, and enabled by default.
+2. Mount propagation feature gate enabled.
+   1. It's enabled by default in Kubernetes v1.10. But some early versions of RKE may not enable it.
+   2. You can check it by using [environment check script](#environment-check-script).
+3. If above conditions cannot be met, Longhorn will fall back to the FlexVolume driver.
+
+### Check if your setup satisfied CSI requirement
+1. Use the following command to check your Kubernetes server version
+```
+kubectl version
+```
+Result:
+```
+Client Version: version.Info{Major:"1", Minor:"10", GitVersion:"v1.10.3", GitCommit:"2bba0127d85d5a46ab4b778548be28623b32d0b0", GitTreeState:"clean", BuildDate:"2018-05-21T09:17:39Z", GoVersion:"go1.9.3", Compiler:"gc", Platform:"linux/amd64"}
+Server Version: version.Info{Major:"1", Minor:"10", GitVersion:"v1.10.1", GitCommit:"d4ab47518836c750f9949b9e0d387f20fb92260b", GitTreeState:"clean", BuildDate:"2018-04-12T14:14:26Z", GoVersion:"go1.9.3", Compiler:"gc", Platform:"linux/amd64"}
+```
+The `Server Version` should be `v1.10` or above.
+
+2. The result of [environment check script](#environment-check-script) should contain `MountPropagation is enabled!`.
+
+### Environment check script
+
+We've wrote a script to help user to gather enough information about the factors
+
+Before installing, run:
+```
+curl -sSfL https://raw.githubusercontent.com/rancher/longhorn/master/scripts/environment_check.sh | bash
+```
+Example result:
+```
+daemonset.apps/longhorn-environment-check created
+waiting for pods to become ready (0/3)
+all pods ready (3/3)
+
+  MountPropagation is enabled!
+
+cleaning up...
+daemonset.apps "longhorn-environment-check" deleted
+clean up complete
+```

+
+
+## Flexvolume
+### Requirement for the FlexVolume driver
+
+1.  Kubernetes v1.8+
+2.  Make sure `curl`, `findmnt`, `grep`, `awk` and `blkid` has been installed in the every node of the Kubernetes cluster.
+
+### Flexvolume driver directory
+
+Longhorn now has ability to auto detect the location of Flexvolume directory.
+
+If the Flexvolume driver wasn't installed correctly, there can be a few reasons:
+1. If `kubelet` is running inside a container rather than running on the host OS, the host bind-mount path for the Flexvolume driver directory (`--volume-plugin-dir`) must be the same as the path used by the kubelet process.
+    1. For example, if the kubelet is using `/var/lib/kubelet/volumeplugins` as
+the Flexvolume driver directory, then the host bind-mount must exist for that
+directory, as e.g. `/var/lib/kubelet/volumeplugins:/var/lib/kubelet/volumeplugins` or any idential bind-mount for the parent directory.
+    2. It's because Longhorn would detect the directory used by the `kubelet` command line to decide where to install the driver on the host.
+2. The kubelet setting for the Flexvolume driver directory must be the same across all the nodes.
+    1. Longhorn doesn't support heterogeneous setup at the moment.
+
+### Successful Flexvolume deployment example
+```
+# kubectl -n longhorn-system get pod

+# Volume Expansion
+
+## Overview
+- Longhorn supports OFFLINE volume expansion only. 
+- Longhorn will expand frontend (e.g. block device) then expand filesystem.
+
+## Prerequisite:
+1. Longhorn version v0.8.0 or higher.
+2. The volume to be expanded is state `detached`.
+
+## Expand a Longhorn volume
+There are two ways to expand a Longhorn volume:
+
+#### Via PVC 
+- This method is applied only if:
+  1. Kubernetes version v1.16 or higher.
+  2. The PVC is dynamically provisioned by the Kubernetes with Longhorn StorageClass.
+  3. The field `allowVolumeExpansion` should be `true` in the related StorageClass.
+- This method is recommended if it's applicable. Since the PVC and PV will be updated automatically and everything keeps consistent after expansion.
+- Usage: Find the corresponding PVC for Longhorn volume then modify requested `storage` of the PVC spec. e.g.,
+```
+apiVersion: v1
+kind: PersistentVolumeClaim
+metadata:
+  annotations:
+    kubectl.kubernetes.io/last-applied-configuration: |
+      {"apiVersion":"v1","kind":"PersistentVolumeClaim","metadata":{"annotations":{},"name":"longhorn-simple-pvc","namespace":"default"},"spec":{"accessModes":["ReadWriteOnce"],"resources":{"requests":{"storage":"1Gi"}},"storageClassName":"longhorn"}}
+    pv.kubernetes.io/bind-completed: "yes"
+    pv.kubernetes.io/bound-by-controller: "yes"
+    volume.beta.kubernetes.io/storage-provisioner: driver.longhorn.io
+  creationTimestamp: "2019-12-21T01:36:16Z"
+  finalizers:
+  - kubernetes.io/pvc-protection
+  name: longhorn-simple-pvc
+  namespace: default
+  resourceVersion: "162431"
+  selfLink: /api/v1/namespaces/default/persistentvolumeclaims/longhorn-simple-pvc
+  uid: 0467ae73-22a5-4eba-803e-464cc0b9d975
+spec:
+  accessModes:
+  - ReadWriteOnce
+  resources:
+    requests:
+      storage: 1Gi
+  storageClassName: longhorn
+  volumeMode: Filesystem
+  volumeName: pvc-0467ae73-22a5-4eba-803e-464cc0b9d975
+status:
+  accessModes:
+  - ReadWriteOnce
+  capacity:
+    storage: 1Gi
+  phase: Bound
+```
+Modify `spec.resources.requests.storage` of this PVC.
+
+
+#### Via Longhorn UI
+- If your Kubernetes version is v1.14 or v1.15, this method is the only choice for Longhorn volume expansion. 
+- Notice that The volume size will be updated after the expansion but the capacity of corresponding PVC and PV won't change. Users need to take care of them.
+- Usage: On the volume page of Longhorn UI, click `Expand` for the volume.
+
+
+## Frontend expansion
+- To prevent the frontend expansion from being interfered by unexpected data R/W, Longhorn supports OFFLINE expansion only. 
+The `detached` volume will be automatically attached to a random node with maintenance mode.
+- Rebuilding/adding replicas is not allowed during the expansion and vice versa. 
+ 
+
+## Filesystem expansion
+#### Longhorn will try to expand the file system only if:
+1. The expanded size should be greater than the current size.
+2. There is a Linux filesystem in the Longhorn volume. 
+3. The filesystem used in the Longhorn volume is one of the followings:
+    1. ext4
+    2. XFS
+4. The Longhorn volume is using block device frontend. 
+
+#### Handling volume revert:
+If users revert a volume to a snapshot with smaller size, the frontend of the volume is still holding the expanded size. But the filesystem size will be the same as that of the reverted snapshot. In this case, users need to handle the filesystem manually:
+  1. Attach the volume to a random nodes.
+  2. Log into the corresponding node, expand the filesystem:
+  - If the filesystem is `ext4`, the volume might need to be mounted and umounted once before resizing the filesystem manually. Otherwise, executing `resize2fs` might result in an error:
+    ```
+    resize2fs: Superblock checksum does not match superblock while trying to open ......
+    Couldn't find valid filesystem superblock.
+    ```
+    Follow the steps below to resize the filesystem:  
+    ```
+    mount /dev/longhorn/<volume name> <arbitrary mount directory>
+    umount /dev/longhorn/<volume name>
+    mount /dev/longhorn/<volume name> <arbitrary mount directory>

+1. GKE clusters must use `Ubuntu` OS instead of `Container-Optimized` OS, in order to satisfy Longhorn `open-iscsi` dependency.
+
+2. GKE requires user to manually claim himself as cluster admin to enable RBAC. Before installing Longhorn, run the following command:
+
+```
+kubectl create clusterrolebinding cluster-admin-binding --clusterrole=cluster-admin --user=<name@example.com>
+
+```
+
+where `name@example.com` is the user's account name in GCE, and it's case sensitive. See [this document](https://cloud.google.com/kubernetes-engine/docs/how-to/role-based-access-control) for more information.

+# iSCSI support
+
+Longhorn supports iSCSI target frontend mode. The user can connect to it
+through any iSCSI client, including open-iscsi, and virtual machine
+hypervisor like KVM, as long as it's in the same network with the Longhorn system.
+
+Longhorn Driver (CSI/Flexvolume) doesn't support iSCSI mode.
+
+To start volume with iSCSI target frontend mode, select `iSCSI` as the frontend
+when creating the volume. After volume has been attached, the user will see
+something like following in the `endpoint` field:
+
+```
+iscsi://10.42.0.21:3260/iqn.2014-09.com.rancher:testvolume/1
+```
+
+Here:
+1. The IP and port is `10.42.0.21:3260`.
+2. The target name is `iqn.2014-09.com.rancher:testvolume`. `testvolume` is the
+   name of the volume.
+3. The LUN number is 1. Longhorn always uses LUN 1.
+
+Then user can use above information to connect to the iSCSI target provided by
+Longhorn using an iSCSI client.

+# Workload identification for volume
+Now users can identify current workloads or workload history for existing Longhorn volumes.
+```
+PV Name: test1-pv
+PV Status: Bound
+
+Namespace: default
+PVC Name: test1-pvc
+
+Last Pod Name: volume-test-1
+Last Pod Status: Running
+Last Workload Name: volume-test
+Last Workload Type: Statefulset
+Last time used by Pod: a few seconds ago
+```
+
+## About historical status
+There are a few fields can contain the historical status instead of the current status. 
+Those fields can be used to help users figuring out which workload has used the volume in the past:
+
+1. `Last time bound with PVC`: If this field is set, it indicates currently there is no bounded PVC for this volume. 
+The related fields will show the most recent bounded PVC. 
+2. `Last time used by Pod`: If these fields are set, they indicates currently there is no workload using this volume. 
+The related fields will show the most recent workload using this volume.
+
+# PV/PVC creation for existing Longhorn volume
+Now users can create PV/PVC via our Longhorn UI for the existing Longhorn volumes. 
+Only detached volume can be used by newly created pod.
+
+## About special fields of PV/PVC
+Since the Longhorn volume already exists while creating PV/PVC, StorageClass is not needed for dynamically provisioning 
+Longhorn volume. However, the field `storageClassName` would be set in PVC/PV, to be used for PVC bounding purpose. And
+it's unnecessary for users create the related StorageClass object. 
+
+By default the StorageClass for Longhorn created PV/PVC is `longhorn-static`. Users can modified it in 
+`Setting - General - Default Longhorn Static StorageClass Name` as they need.
+
+Users need to manually delete PVC and PV created by Longhorn.

+## Create Nginx Ingress Controller with basic authentication
+
+1. Create a basic auth file `auth`:
+> It's important the file generated is named auth (actually - that the secret has a key data.auth), otherwise the ingress-controller returns a 503
+
+`$ USER=<USERNAME_HERE>; PASSWORD=<PASSWORD_HERE>; echo "${USER}:$(openssl passwd -stdin -apr1 <<< ${PASSWORD})" >> auth`
+
+2. Create a secret
+
+`$ kubectl -n longhorn-system create secret generic basic-auth --from-file=auth`
+
+3. Create an Nginx ingress controller manifest `longhorn-ingress.yml` :
+
+```
+apiVersion: networking.k8s.io/v1beta1

+  name: longhorn-ingress
+  namespace: longhorn-system
+  annotations:
