36 | # DESCRIPTION: | |
37 | # | |
38 | # Setting a reservation on dataset should have no effect on any other | |
39 | # dataset at the same level in the hierarchy beyond using up available | |
40 | # space in the pool. | |
41 | # | |
42 | # STRATEGY: | |
43 | # 1) Create a filesystem | |
44 | # 2) Set a reservation on the filesystem | |
45 | # 3) Create another filesystem at the same level | |
46 | # 4) Set a reservation on the second filesystem | |
47 | # 5) Destroy both the filesystems | |
48 | # 6) Verify space accounted for correctly | |
