Hello team:

[ Description ]:
While running StorageClass Conversion using MTC over a volume that was successfully restored with OADP, we encountered the following errors:

2m53s       Normal    Provisioning           persistentvolumeclaim/xxxxxxx   External provisioner is provisioning volume for claim "yyyyyyyyyyy/xxxxxxx"
2m53s       Warning   ProvisioningFailed     persistentvolumeclaim/xxxxxxxx   failed to provision volume with StorageClass "ocs-storagecluster-cephfs": claim Selector is not supported
 

Checking on the PVC definition that is being converted, we noticed that it comes with a selector label: 

$ oc get pvc xxxxxxxxx -o yaml |yq '.spec.selector'
{
  "matchLabels": {
    "velero.io/dynamic-pv-restore": "xxxxxxxxxxx"
  }
}
 

According to the following KCS or Kubernetes documentation, dynamically provisioned PVC's even if they are restored, should not come with a selector:

• https://kubernetes.io/docs/concepts/storage/persistent-volumes/#class-1
•  

This ticket is a follow-up to analyze if this could be fixed from the MTC perspective, as per OADP engineering determined in https://issues.redhat.com/browse/OADP-6507
