40#
41# DESCRIPTION:
42#
43# Reservation values cannot exceed the amount of space available
44# in the pool. Verify that attempting to set a reservation greater
45# than this value fails.
46#
47# STRATEGY:
48# 1) Create a filesystem, regular and sparse volume
49# 2) Get the space available in the pool
50# 3) Attempt to set a reservation greater than the available space
51# on the filesystem and verify it fails.
52# 4) Verify that the reservation is still set to 'none' (or 0) on
53# the filesystem.
54# 5) Repeat 3-4 for regular and sparse volume
55#
56# TESTABILITY: explicit
57#
58# TEST_AUTOMATION_LEVEL: automated
59#
60# CODING_STATUS: COMPLETED (2005-07-19)
