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