# ID: hotspare_clone_001_pos
#
# DESCRIPTION: 
#	If a storage pool has activated hot spares, 
#	create clone and remove the hot spare,
#	the data in clone should keep integrity.
#
# STRATEGY:
#	1. Create a storage pool with hot spares
#	2. Create some files, create a snapshot & clone upon filesystem
#	3. Activate a spare device to the pool
#	4. Create some files, create an new snapshot & clone upon filesystem
#	5. Do 'zpool detach' with the spare in device
#	6. Verify the 2 clones are all kept, and verify the data integrity within them.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING STATUS: COMPLETED (2006-06-07)
