3. Longhorn Share Manager -- NFS provisioner that exposes Longhorn volumes as ReadWriteMany volumes. https://github.com/longhorn/longhorn-share-manager
4. Longhorn Manager -- Longhorn orchestration, includes CSI driver for Kubernetes https://github.com/longhorn/longhorn-manager
4. Longhorn UI -- Dashboard https://github.com/longhorn/longhorn-ui
## Prerequisites
1. Docker v1.13+
2. Kubernetes v1.15+
2. Kubernetes v1.16+
3. Make sure `curl`, `findmnt`, `grep`, `awk` and `blkid` has been installed in all nodes of the Kubernetes cluster.
4. 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.

The value is how many CPUs should be reserved for each Engine/Replica Instance Manager Pod created by Longhorn. For example, 0.1 means one-tenth of a CPU. This will help maintain engine stability during high node workload. It only applies to the Engine/Replica Instance Manager Pods created after the setting took effect.
In order to prevent unexpected volume crash, you can use the following formula to calculate an appropriate value for this setting:
'Guaranteed Engine CPU = The estimated max Longhorn volume/replica count on a node * 0.1'.
The result of above calculation doesn't mean that's the maximum CPU resources the Longhorn workloads require. To fully exploit the Longhorn volume I/O performance, you can allocate/guarantee more CPU resources via this setting.
If it's hard to estimate the volume/replica count now, you can leave it with the default value, or allocate 1/8 of total CPU of a node. Then you can tune it when there is no running workload using Longhorn volumes.
