  22 # DESCRIPTION:
  23 # A pool that wasn't cleanly exported should not be importable from a cachefile
  24 # without force if the local hostid doesn't match the on-disk hostid.
  25 #
  26 # STRATEGY:
  27 #       1. Set a hostid.
  28 #       2. Create a pool.
  29 #       3. Backup the cachefile.
  30 #       4. Simulate the pool being torn down without export:
  31 #       4.1. Copy the underlying device state.
  32 #       4.2. Export the pool.
  33 #       4.3. Restore the device state from the copy.
  34 #       5. Change the hostid.
  35 #       6. Verify that importing the pool from the cachefile fails.
  36 #       7. Verify that importing the pool from the cachefile with force
  37 #          succeeds.
