41# DESCRIPTION:
42#
43# Reservations (if successfully set) guarantee a minimum amount of space
44# for a dataset. Unlike quotas however there should be no restrictions
45# on accessing space outside of the limits of the reservation (if the
46# space is available in the pool). Verify that in a filesystem with a
47# reservation set that its possible to create files both within the
48# reserved space and also outside.
49#
50# STRATEGY:
51# 1) Create a filesystem
52# 2) Get the space used and available in the pool
53# 3) Set a reservation on the filesystem
54# 4) Verify can write a file that is bigger than the reserved space
55#
56# i.e. we start writing within the reserved region and then continue
57# for 20MB outside it.
58#
59# TESTABILITY: explicit
60#
61# TEST_AUTOMATION_LEVEL: automated
62#
63# CODING_STATUS: COMPLETED (2005-07-04)
