35# DESCRIPTION:
36# Valid reservation values should be positive integers only.
37#
38# STRATEGY:
39# 1) Form an array of invalid reservation values (negative and
40# incorrectly formed)
41# 2) Attempt to set each invalid reservation value in turn on a
42# filesystem and volume.
43# 3) Verify that attempt fails and the reservation value remains
44# unchanged
