# DESCRIPTION:
# 'zfs rename' can successfully rename a volume snapshot.
#
# STRATEGY:
# 1. Create a snapshot of volume.
# 2. Rename volume snapshot to a new one.
# 3. Rename volume to a new one.
# 4. Create a clone of the snapshot.
# 5. Verify that the rename operations are successful and zfs list can
# list them.
