36# DESCRIPTION:
37#
38# For a sparse volume changes to the volsize are not reflected in the
39# reservation.
40#
41# STRATEGY:
42# 1) Create a regular and sparse volume
43# 2) Get the space available in the pool
44# 3) Set reservation with various sizes on the regular and sparse volumes
45# 4) Verify that the 'reservation' property for the regular volume has
46#    the correct value.
47# 5) Verify that the 'reservation' property for the sparse volume is set to
48#    'none'
