# ID: zpool_destroy_002_pos
#
# DESCRIPTION: 
#	'zpool destroy -f <pool>' can forcely destroy the specified pool.
#
# STRATEGY:
#	1. Create a storage pool
#	2. Create some datasets within the pool
#	3. Change directory to any mountpoint of these datasets, 
#	   Verify 'zpool destroy' without '-f' will fail.
#	4. 'zpool destroy -f' the pool
#	5. Verify the pool is destroyed successfully
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-07-04)
