36#
37# DESCRIPTION:
38#	If a hot spare have been activated, create snapshot upon filesystem,
39#	then invoke "zpool detach" with this hot spare,
40#	the data in snapshot should untouched.
41#
42# STRATEGY:
43#	1. Create a storage pool with hot spares
44#	2. Create some files, create a snapshot upon filesystem
45#	3. Activate a spare device to the pool
46#	4. Create some files, create an new snapshot upon filesystem
47#	5. Do 'zpool detach' with the spare in device
48#	6. Verify the 2 snapshots are all kept, and verify the data integrity within them.
49#
50# TESTABILITY: explicit
51#
52# TEST_AUTOMATION_LEVEL: automated
53#
54# CODING STATUS: COMPLETED (2006-06-07)
