35#
36# DESCRIPTION:
37#
38# ZFS allows reservations to be set on filesystems and volumes, provided
39# the reservation is less than the space available in the pool.
40#
41# STRATEGY:
42# 1) Create a regular and sparse volume
43#   (filesystem already created by default_setup)
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) Reset the reservation to 'none'
49# 6) Repeat steps 2-5 for both volume types
50#
51# TESTABILITY: explicit
52#
53# TEST_AUTOMATION_LEVEL: automated
54#
55# CODING_STATUS: COMPLETED (2005-07-19)
