| # DESCRIPTION: |
| # |
| # A reservation cannot exceed the quota on a dataset |
| # |
| # STRATEGY: |
| # 1) Create a filesystem and volume |
| # 2) Set a quota on the filesystem |
| # 3) Attempt to set a reservation larger than the quota. Verify |
| # that the attempt fails. |
| # 4) Repeat 2-3 for volume |
| # |
