35# DESCRIPTION:
36#	Verify a snapshot will only be allowed if there is enough free pool
37#	space outside of this refreservation.
38#
39# STRATEGY:
40#	1. Setting quota and refservation
41#	2. Verify snapshot can be created, when used =< quota - refreserv
42#	3. Verify failed to create snapshot, when used > quota - refreserv
43#
44# TESTABILITY: explicit
45#
46# TEST_AUTOMATION_LEVEL: automated
47#
48# CODING_STATUS: COMPLETED (2007-11-05)
