| # DESCRIPTION: |
| # |
| # Verify that it's possible to set a reservation on a filesystem, |
| # or volume multiple times, without resetting the reservation |
| # to none. |
| # |
| # STRATEGY: |
| # 1) Create a regular volume and a sparse volume |
| # 2) Get the space available in the pool |
| # 3) Set a reservation on the filesystem less than the space available. |
| # 4) Verify that the 'reservation' property for the filesystem has |
| # the correct value. |
| # 5) Repeat 2-4 for different reservation values |
| # 6) Repeat 3-5 for regular and sparse volume |
| # |
