# DESCRIPTION:
#
# Verify that it's possible to set a reservation on a filesystem,
# or volume multiple times, without resetting the reservation
# to none.
#
# STRATEGY:
# 1) Create a regular volume and a sparse volume
# 2) Get the space 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) Repeat 2-4 for different reservation values
# 6) Repeat 3-5 for regular and sparse volume
