  21 # DESCRIPTION:
  22 #       A pool should be importable using an outdated cachefile that is unaware
  23 #       that one or more vdevs were removed.
  24 #
  25 # STRATEGY:
  26 #       1. Create a pool with some devices and an alternate cachefile.
  27 #       2. Backup the cachefile.
  28 #       3. Remove device(s) from the pool and remove them.
  29 #       4. (Optionally) Add device(s) to pool.
  30 #       5. Export the pool.
  31 #       6. Verify that we can import the pool using the backed-up cachefile.
