40# DESCRIPTION:
41#	Verify a snapshot will only be allowed if there is enough free pool
42#	space outside of this refreservation.
43#
44# STRATEGY:
45#	1. Setting quota and refservation
46#	2. Verify snapshot can be created, when used =< quota - refreserv
47#	3. Verify failed to create snapshot, when used > quota - refreserv
48#
49# TESTABILITY: explicit
50#
51# TEST_AUTOMATION_LEVEL: automated
52#
53# CODING_STATUS: COMPLETED (2007-11-05)
