  36 # DESCRIPTION:
  37 #       Turning a disk offline and back online during I/O completes.
  38 #
  39 # STRATEGY:
  40 #       1. Create a mirror and start some random I/O
  41 #       2. For each disk in the mirror, set it offline and online
  42 #       3. Verify the integrity of the file system and the resilvering.
