21# DESCRIPTION:
22#	A pool should be importable using an outdated cachefile that is unaware
23#	that a mirror was detached.
24#
25# STRATEGY:
26#	1. Create a pool with some devices mirrored and an alternate cachefile.
27#	2. Backup the cachefile.
28#	3. Detach a mirror from the pool.
29#	4. Export the pool.
30#	5. Verify that we can import the pool using the backed-up cachefile.
