| # DESCRIPTION: |
| # |
| # Setting a reservation on dataset should have no effect on any other |
| # dataset at the same level in the hierarchy beyond using up available |
| # space in the pool. |
| # |
| # STRATEGY: |
| # 1) Create a filesystem |
| # 2) Set a reservation on the filesystem |
| # 3) Create another filesystem at the same level |
| # 4) Set a reservation on the second filesystem |
| # 5) Destroy both the filesystems |
| # 6) Verify space accounted for correctly |
| # |
