  36 # DESCRIPTION:
  37 # format will disallow modification of a mounted zfs disk partition or a spare
  38 # device
  39 #
  40 # STRATEGY:
  41 # 1. Create a ZFS filesystem
  42 # 2. Add a spare device to the ZFS pool
  43 # 3. Attempt to format the disk and the spare device.

  66 # would happily continue - best to not go further.
