Pod failed due to error "Unable to attach or mount volumes: unmounted volumes=[registry-storage]" timed out waiting for the condition for Netapp Trident storage PV.

Issue

• After the cluster upgrade the registry pod fails with FailedMount error.

50s         Warning   FailedMount          pod/image-registry-xxxx-yyyy    Unable to attach or mount volumes: unmounted volumes=[registry-storage], unattached volumes=[registry-token-swzgd registry-storage registry-tls registry-certificates trusted-ca]: timed out waiting for the condition

• PV is present on the system but still registry pod fails with error as FailedMount.
• The creation of a new pod with new PV is working fine, but the issue is with all existing pods having old PV reference, as they failed with FailedMount error even after PV is present.
