38#
39# DESCRIPTION:
40#
41# Verify that it's possible to set a reservation on a filesystem,
42# or volume multiple times, without resetting the reservation
43# to none.
44#
45# STRATEGY:
46# 1) Create a regular volume and a sparse volume
47# 2) Get the space available in the pool
48# 3) Set a reservation on the filesystem less than the space available.
49# 4) Verify that the 'reservation' property for the filesystem has
50# the correct value.
51# 5) Repeat 2-4 for different reservation values
52# 6) Repeat 3-5 for regular and sparse volume
53#
54# TESTABILITY: explicit
55#
56# TEST_AUTOMATION_LEVEL: automated
57#
58# CODING_STATUS: COMPLETED (2005-07-19)
