# 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.
