35# DESCRIPTION:
36#	Verify refreservation is limited by available space.
37#
38# STRATEGY:
39#	1. Setting quota and refreservation on parent filesystem.
40#	2. Get available space on sub-filesystem.
41#	3. Verify refreservation is limited by available on it.
42#
43# TESTABILITY: explicit
44#
45# TEST_AUTOMATION_LEVEL: automated
46#
47# CODING_STATUS: COMPLETED (2007-11-05)
