# ID: refquota_005_pos
#
# DESCRIPTION:
#	refquotas are not limited by sub-filesystem snapshots.
#
# STRATEGY:
#	1. Setting refquota < quota for parent
#	2. Create file in sub-filesytem, take snapshot and remove the file
#	3. Verify sub-filesystem snapshot will not consume refquota 
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2007-11-02)
