-### RBD VolumeGroupSnapshotClass

-In [VolumeGroupSnapshotClass](https://github.com/rook/rook/tree/master/deploy/examples/csi/rbd/groupsnapshotclass.yaml),
-the `csi.storage.k8s.io/group-snapshotter-secret-name` parameter references the
-name of the secret created for the rbd-plugin and `pool` to reflect the Ceph pool name.
-
-In the `VolumeGroupSnapshotClass`, update the value of the `clusterID` field to match the namespace
-that Rook is running in. When Ceph CSI is deployed by Rook, the operator will automatically
-maintain a configmap whose contents will match this key. By default this is
-"rook-ceph".

-In [VolumeGroupSnapshot](https://github.com/rook/rook/tree/master/deploy/examples/csi/rbd/groupsnapshot.yaml),
-`volumeGroupSnapshotClassName` is the name of the `VolumeGroupSnapshotClass`
-previously created. The labels inside `matchLabels` must be present on the
-PVCs that are already created by the RBD CSI driver.
