# ID: refquota_002_pos
#
# DESCRIPTION:
#	Quotas are enforced using the minimum of the two properties: 
#	quota & refquota
#
# STRATEGY:
#	1. Set value for quota and refquota. Quota less than refquota.
#	2. Creating file which should be limited by quota.
#	3. Switch the value of quota and refquota.
#	4. Verify file should be limited by refquota.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2007-11-02)
