# ID: refquota_001_pos
#
# DESCRIPTION:
#	refquota limits the amount of space a dataset can consume, but does
#	not include space used by descendents.
#
# STRATEGY:
#	1. Setting refquota in given filesystem
#	2. Create descendent filesystem
#	3. Verify refquota limits the amount of space a dataset can consume
#	4. Verify the limit does not impact descendents
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2007-12-13)
#
