consider support of csi snapshots about csi-driver-lvm

[mwennrich]

The use case for snapshots is, to create a pvc from an existing snapshot via dataSource. Example:

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: restore-pvc
spec:
  storageClassName: csi-hostpath-sc
  dataSource:
    name: new-snapshot-test
    kind: VolumeSnapshot
    apiGroup: snapshot.storage.k8s.io

But for local volumes we have to use volumeBindingMode: WaitForFirstConsumer, so this doesn't work if the scheduler schedules the first consumer pod to another worker node, since on this worker node that snapshot isn't available. There are no "local snapshots" in k8s ...

OK, i thought the use case would be for backups in the first place. Thanks for clarification, closing.
