# DESCRIPTION:
#
# For a sparse volume changes to the volsize are not reflected in the
# reservation.
#
# STRATEGY:
# 1) Create a regular and sparse volume
# 2) Get the space available in the pool
# 3) Set reservation with various sizes on the regular and sparse volumes
# 4) Verify that the 'reservation' property for the regular volume has
# the correct value.
# 5) Verify that the 'reservation' property for the sparse volume is set to
# 'none'
#
