35#
36# DESCRIPTION:
37#
38# When a reservation property of a filesystem, regular volume
39# or sparse volume is set to 'none' the space previously consumed by the
40# reservation should be released back to the pool
41#
42# STRATEGY:
43# 1) Create a filesystem, regular volume and sparse volume
44# 2) Get the space used and available in the pool
45# 3) Set a reservation on the filesystem less than the space available.
46# 4) Verify that the 'reservation' property for the filesystem has
47# the correct value.
48# 5) Reset the reservation value back to zero (or 'none')
49# 6) Verify that the space used and available totals for the pool have
50# changed by the expected amounts (within tolerances).
51# 7) Repeat steps 3-6 for a regular volume, sparse volume
52#
53# TESTABILITY: explicit
54#
55# TEST_AUTOMATION_LEVEL: automated
56#
57# CODING_STATUS: COMPLETED (2005-07-04)
