  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  22 #       A pool should be importable using an outdated cachefile that is unaware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.
