Verify the metadata for RBD clone

Procedure

  1. Create a clone. 
    cat <<EOF | oc create -f -apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: rbd-pvc-clone
spec:
  storageClassName: ocs-storagecluster-ceph-rbd
  dataSource:
    name: rbd-pvc
    kind: PersistentVolumeClaim
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi
EOF
  2. Check the status of the clone. 
    oc get pvc | grep rbd-pvc
    
rbd-pvc                           Bound    pvc-30628fa8-2966-499c-832d-a6a3a8ebc594   1Gi        RWO            ocs-storagecluster-ceph-rbd   15m
rbd-pvc-clone                     Bound    pvc-0d72afda-f433-4d46-a7f1-a5fcb3d766e0   1Gi        RWO            ocs-storagecluster-ceph-rbd   52s
  3. Verify the metadata in the IBM Storage Ceph command-line interface (CLI). 
    rbd ls ocs-storagecluster-cephblockpool
