# DESCRIPTION:
#	'zfs destroy <filesystem|volume|snapshot>' can successfully destroy
#	the specified dataset which has no active dependents.
#
# STRATEGY:
#	1. Create a filesystem,volume and snapshot in the storage pool
#	2. Destroy the filesystem,volume and snapshot
#	3. Verify the datasets are destroyed successfully
