39# DESCRIPTION:
40#	If a storage pool has activated hot spares,
41#	create clone and then invoke "zpool detach" with the original device,
42#	the data in clone should keep integrity.
43#
44# STRATEGY:
45#	1. Create a storage pool with hot spares activated.
46#	2. Create some files, create a snapshot & clone upon filesystem
47#	3. Activate a spare device to the pool
48#	4. Create some files, create an new snapshot & clone upon filesystem
49#	5. Do 'zpool detach' with the original device
50#	6. Verify the 2 clones are all kept, and verify the data integrity within them.
51#
52# TESTABILITY: explicit
53#
54# TEST_AUTOMATION_LEVEL: automated
55#
56# CODING STATUS: COMPLETED (2006-06-07)
