Volume snapshot support
Volume snapshot support for the storage class must be installed in your OpenShift cluster.
Run the following commands to determine whether or not volume support for the storage class is installed in your OpenShift cluster:
kubectl get sc NAME PROVISIONER RECLAIMPOLICY VOLUMEBINDINGMODE ALLOWVOLUMEEXPANSION AGE cdw-scratch kubernetes.io/no-provisioner Delete WaitForFirstConsumer false 82d localblock kubernetes.io/no-provisioner Delete WaitForFirstConsumer false 82d nfs nfs-server-provisioner Delete Immediate true 82d ocs-storagecluster-ceph-rbd (default) openshift-storage.rbd.csi.ceph.com Delete Immediate true 82d ocs-storagecluster-ceph-rgw openshift-storage.ceph.rook.io/bucket Delete Immediate false 82d ocs-storagecluster-cephfs openshift-storage.cephfs.csi.ceph.com Delete Immediate true 82d openshift-storage.noobaa.io openshift-storage.noobaa.io/obc Delete Immediate false 82d

A storage class has a volume snapshot installed if there is an entry with the value in the DRIVER column returned by the second command that matches one of the values in the PROVISIONER column returned by the first command. In the example above, the following storage classes have volume snapshot support:
