#
# DESCRIPTION:
#       Check user|group quota to snapshot that:
#	1) can not set user|group quota to snapshot directly
#	2) snapshot can inherit the parent fs's user|groupquota
#	3) the user|group quota will not change even the parent fs's quota changed.
#
#
# STRATEGY:
#       1. create a snapshot of a fs
#       2. set the user|group quota to snapshot and expect fail
#	3. set user|group quota to fs and check the snapshot
#	4. re-set user|group quota to fs and check the snapshot's value
#
