36# DESCRIPTION:
37#
38# A reservation cannot exceed the quota on a dataset
39#
40# STRATEGY:
41# 1) Create a filesystem and volume
42# 2) Set a quota on the filesystem
43# 3) Attempt to set a reservation larger than the quota. Verify
44# that the attempt fails.
45# 4) Repeat 2-3 for volume
46#
47# TESTABILITY: explicit
48#
49# TEST_AUTOMATION_LEVEL: automated
50#
51# CODING_STATUS: COMPLETED (2005-07-04)
