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.

64# Currently, if a ZFS disk gets formatted things go horribly wrong, hence the
65# mini_format function.  If the modify option is reached, then we know format
66# would happily continue - best to not go further.
