Verify the metadata for RBD snapshots

Procedure

  1. Create a snapshot. 
    cat <<EOF | oc create -f -
apiVersion: snapshot.storage.k8s.io/v1
kind: VolumeSnapshot
metadata:
  name: rbd-pvc-snapshot
spec:
  volumeSnapshotClassName: ocs-storagecluster-rbdplugin-snapclass
  source:
    persistentVolumeClaimName: rbd-pvc
EOF
volumesnapshot.snapshot.storage.k8s.io/rbd-pvc-snapshot created
  2. Check the status of the snapshot. 
    oc get volumesnapshot
