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