36# DESCRIPTION:
37#
38# For a sparse volume changes to the volsize are not reflected in the reservation
39#
40# STRATEGY:
41# 1) Create a regular and sparse volume
42# 2) Get the space available in the pool
43# 3) Set reservation with various size on the regular and sparse volume
44# 4) Verify that the 'reservation' property for the regular volume has
45#    the correct value.
46# 5) Verify that the 'reservation' property for the sparse volume is set to 'none'
47#
48# TESTABILITY: explicit
49#
50# TEST_AUTOMATION_LEVEL: automated
51#
52# CODING_STATUS: COMPLETED (2006-08-17)
