  21 # DESCRIPTION:
  22 #       A pool should be importable even if device paths have changed.
  23 #
  24 # STRATEGY:
  25 #       1. Create a pool.
  26 #       2. Export the pool.
  27 #       3. Change the paths of some of the devices.
  28 #       4. Verify that we can import the pool in a healthy state.
