StorageClass volPrefix has no effect to the volume name

[dewongway]

Describe the bug
I am not sure what the volPrefix supposed to do. When I set it to csi-me5, I don't see it being taken into consideration for the PVC name, PV name, or the volume name on the storage array.

To Reproduce
Steps to reproduce the behavior:

Set volPrefix in the storageclass and create a PV using the storage class.

apiVersion: storage.k8s.io/v1
kind: StorageClass
provisioner: csi-exos-x.seagate.com
volumeBindingMode: WaitForFirstConsumer
allowVolumeExpansion: true
metadata:
  name: me5-2-storageclass2
parameters:
  csi.storage.k8s.io/provisioner-secret-name: seagate-exos-x-csi-secrets
  csi.storage.k8s.io/provisioner-secret-namespace: seagate
  csi.storage.k8s.io/controller-publish-secret-name: seagate-exos-x-csi-secrets
  csi.storage.k8s.io/controller-publish-secret-namespace: seagate
  csi.storage.k8s.io/controller-expand-secret-name: seagate-exos-x-csi-secrets
  csi.storage.k8s.io/controller-expand-secret-namespace: seagate
  fsType: ext4
  pool: A
  volPrefix: csi-me5
  storageProtocol: iscsi

$ kubectl get pvc -n test-seagate
NAME         STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS          AGE

$ kubectl get pv -n test-seagate

Expected behavior
I expect to see the prefix as part of the volume name.

Thanks, we're looking into this now.

The limit for the VolNamePrefix parameter is 3 characters, so your input "csi-me5" was silently truncated to "csi". We'll update the examples and add a warning in the logs to make this clearer.

Great. Thanks for the info.
