37#
38# DESCRIPTION:
39#
40# Can't set a quota to less than currently being used by the dataset.
41#
42# STRATEGY:
43# 1) Create a filesystem
44# 2) Set a quota on the filesystem that is lower than the space
45#	currently in use.
46# 3) Verify that the attempt fails.
47#
48# TESTABILITY: explicit
49#
50# TEST_AUTOMATION_LEVEL: automated
51#
52# CODING_STATUS: COMPLETED (2006-09-13)
