  37 # DESCRIPTION:
  38 #       Detaching disks during I/O should pass for supported pools.
  39 #
  40 # STRATEGY:
  41 #       1. Create multidisk pools (stripe/mirror/raidz) and
  42 #          start some random I/O
  43 #       2. Detach a disk from the pool.
  44 #       3. Verify the integrity of the file system and the resilvering.
