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