33#
34# DESCRIPTION:
35#	If a hot spare have been activated, create snapshot upon filesystem,
36#	then invoke "zpool detach" with this hot spare,
37#	the data in snapshot should untouched.
38#
39# STRATEGY:
40#	1. Create a storage pool with hot spares
41#	2. Create some files, create a snapshot upon filesystem
42#	3. Activate a spare device to the pool
43#	4. Create some files, create an new snapshot upon filesystem
44#	5. Do 'zpool detach' with the spare in device
45#	6. Verify the 2 snapshots are all kept, and verify the data integrity within them.
46#
47# TESTABILITY: explicit
48#
49# TEST_AUTOMATION_LEVEL: automated
50#
51# CODING STATUS: COMPLETED (2006-06-07)
