36# DESCRIPTION:
37#
38# Reservation values cannot exceed the amount of space available
39# in the pool. Verify that attempting to set a reservation greater
40# than this value fails.
41#
42# STRATEGY:
43# 1) Create a filesystem, regular and sparse volume
44# 2) Get the space available in the pool
45# 3) Attempt to set a reservation greater than the available space
46# on the filesystem and verify it fails.
47# 4) Verify that the reservation is still set to 'none' (or 0) on
48# the filesystem.
49# 5) Repeat 3-4 for regular and sparse volume
50#
