40#
41# DESCRIPTION:
42#
43# ZFS allows reservations to be set on filesystems and volumes, provided
44# the reservation is less than the space available in the pool.
45#
46# STRATEGY:
47# 1) Create a regular and sparse volume
48#   (filesystem already created by default_setup)
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) Reset the reservation to 'none'
54# 6) Repeat steps 2-5 for both volume types
55#
56# TESTABILITY: explicit
57#
58# TEST_AUTOMATION_LEVEL: automated
59#
60# CODING_STATUS: COMPLETED (2005-07-19)
