# ID: zfs_destroy_002_pos
#
# 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
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2006-06-07)
