34#
35# DESCRIPTION:
36#
37# Can't set a quota to less than currently being used by the dataset.
38#
39# STRATEGY:
40# 1) Create a filesystem
41# 2) Set a quota on the filesystem that is lower than the space
42#	currently in use.
43# 3) Verify that the attempt fails.
44#
45# TESTABILITY: explicit
46#
47# TEST_AUTOMATION_LEVEL: automated
48#
49# CODING_STATUS: COMPLETED (2006-09-13)
