CSI driver does not work with Retain Policy DELETE on static PV

[przem123]

I have reclaim policy DELETE on my directory from a remote fs:

[root@worker01 tools]# oc describe pv pv-images
Name:            pv-images
Labels:          id=test1
Annotations:     kubectl.kubernetes.io/last-applied-configuration:

    ReadOnly:          false
    VolumeAttributes:  <none>

When I remove the corresponding PVC, then the PV goes into a failed state. Nothing will be removed.

status:
  phase: Failed
  message: >-
    Error getting deleter volume plugin for volume "pv-images": no volume plugin
    matched

Please fix it so that I can use reclaim policy DELETE on static PVs so that the data is then removed automatically.

For static PV, CSI driver hasn't provisioned the volume so PV doesn't have information of the provisioner and that's the reason we get "no volume plugin matched". Since CSI driver didn't created the volume hence delete will also not be called. For Static volume end user has to manually delete the PV.

However there are certain ways to accomplish delete by updating static pv yaml with provisioner name something as below

metadata:
name: mystaticpv
annotations:
pv.kubernetes.io/provisioned-by: spectrumscale.csi.ibm.com

This is working as per design for IBM Spectrum Scale CSI Driver. The statically provisioned pv will not get deleted by deleting the pvc.
