# DESCRIPTION:
# format will disallow modification of a mounted zfs disk partition or a spare
# device
#
# STRATEGY:
# 1. Create a ZFS filesystem
# 2. Add a spare device to the ZFS pool
# 3. Attempt to format the disk and the spare device.

# Currently, if a ZFS disk gets formatted things go horribly wrong, hence the
