40#
41# DESCRIPTION:
42#
43# When a reservation property of a filesystem, regular volume
44# or sparse volume is set to 'none' the space previously consumed by the
45# reservation should be released back to the pool
46#
47# STRATEGY:
48# 1) Create a filesystem, regular volume and sparse volume
49# 2) Get the space used and available in the pool
50# 3) Set a reservation on the filesystem less than the space available.
51# 4) Verify that the 'reservation' property for the filesystem has
52# the correct value.
53# 5) Reset the reservation value back to zero (or 'none')
54# 6) Verify that the space used and available totals for the pool have
55# changed by the expected amounts (within tolerances).
56# 7) Repeat steps 3-6 for a regular volume, sparse volume
57#
58# TESTABILITY: explicit
59#
60# TEST_AUTOMATION_LEVEL: automated
61#
62# CODING_STATUS: COMPLETED (2005-07-04)
