# ID: quota_006_neg
#
# DESCRIPTION:
#
# Can't set a quota to less than currently being used by the dataset.
#
# STRATEGY:
# 1) Create a filesystem
# 2) Set a quota on the filesystem that is lower than the space
#	currently in use.
# 3) Verify that the attempt fails.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2006-09-13)
