# DESCRIPTION:
|
|
#
|
|
# When a reservation property of a filesystem, regular volume
|
|
# or sparse volume is set to 'none' the space previously consumed by the
|
|
# reservation should be released back to the pool
|
|
#
|
|
# STRATEGY:
|
|
# 1) Create a filesystem, regular volume and sparse volume
|
|
# 2) Get the space used and available in the pool
|
|
# 3) Set a reservation on the filesystem less than the space available.
|
|
# 4) Verify that the 'reservation' property for the filesystem has
|
|
# the correct value.
|
|
# 5) Reset the reservation value back to zero (or 'none')
|
|
# 6) Verify that the space used and available totals for the pool have
|
|
# changed by the expected amounts (within tolerances).
|
|
# 7) Repeat steps 3-6 for a regular volume, sparse volume
|
|
