40# DESCRIPTION:
41#	Verify refreservation is limited by available space.
42#
43# STRATEGY:
44#	1. Setting quota and refreservation on parent filesystem.
45#	2. Get available space on sub-filesystem.
46#	3. Verify refreservation is limited by available on it.
47#
48# TESTABILITY: explicit
49#
50# TEST_AUTOMATION_LEVEL: automated
51#
52# CODING_STATUS: COMPLETED (2007-11-05)
