40#
41# DESCRIPTION:
42#
43# Verify that it's possible to set a reservation on a filesystem,
44# or volume multiple times, without resetting the reservation
45# to none.
46#
47# STRATEGY:
48# 1) Create a regular volume and a sparse volume
49# 2) Get the space 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) Repeat 2-4 for different reservation values
54# 6) Repeat 3-5 for regular and sparse volume
55#
56# TESTABILITY: explicit
57#
58# TEST_AUTOMATION_LEVEL: automated
59#
60# CODING_STATUS: COMPLETED (2005-07-19)
