36 | # DESCRIPTION: | |
37 | # | |
38 | # ZFS allows reservations to be set on filesystems and volumes, provided | |
39 | # the reservation is less than the space available in the pool. | |
40 | # | |
41 | # STRATEGY: | |
42 | # 1) Create a regular and sparse volume | |
43 | # (filesystem already created by default_setup) | |
44 | # 2) Get the space available in the pool | |
45 | # 3) Set a reservation on the filesystem less than the space available. | |
46 | # 4) Verify that the 'reservation' property for the filesystem has | |
47 | # the correct value. | |
48 | # 5) Reset the reservation to 'none' | |
49 | # 6) Repeat steps 2-5 for both volume types | |
50 | # | |
