  36 # DESCRIPTION:
  37 #       Resilver prevent scrub from starting until the resilver completes
  38 #
  39 # STRATEGY:
  40 #       1. Setup a mirror pool and filled with data.
  41 #       2. Detach one of devices
  42 #       3. Create a file for the resilver to work on so it takes some time
  43 #       4. Export/import the pool to ensure the cache is dropped
  44 #       5. Verify scrub failed until the resilver completed
  45 #
