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