35#
36# DESCRIPTION:
37#
38# Verify that it's possible to set a reservation on a filesystem,
39# or volume multiple times, without resetting the reservation
40# to none.
41#
42# STRATEGY:
43# 1) Create a regular volume and a sparse volume
44# 2) Get the space 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) Repeat 2-4 for different reservation values
49# 6) Repeat 3-5 for regular and sparse volume
50#
51# TESTABILITY: explicit
52#
53# TEST_AUTOMATION_LEVEL: automated
54#
55# CODING_STATUS: COMPLETED (2005-07-19)
