36# DESCRIPTION:
37#
38# Reservations (if successfully set) guarantee a minimum amount of space
39# for a dataset. Unlike quotas however there should be no restrictions
40# on accessing space outside of the limits of the reservation (if the
41# space is available in the pool). Verify that in a filesystem with a
42# reservation set that its possible to create files both within the
43# reserved space and also outside.
44#
45# STRATEGY:
46# 1) Create a filesystem
47# 2) Get the space used and available in the pool
48# 3) Set a reservation on the filesystem
49# 4) Verify can write a file that is bigger than the reserved space
50#
51# i.e. we start writing within the reserved region and then continue
52# for 20MB outside it.
53#
54# TESTABILITY: explicit
55#
56# TEST_AUTOMATION_LEVEL: automated
57#
58# CODING_STATUS: COMPLETED (2005-07-04)
