| # DESCRIPTION: |
| # 'zfs rollback -r|-rf|-R|-Rf' will recursively destroy any snapshots |
| # more recent than the one specified. |
| # |
| # STRATEGY: |
| # 1. Create pool, fs & volume. |
| # 2. Separately create three snapshots or clones for fs & volume |
| # 3. Roll back to the second snapshot and check the results. |
| # 4. Create the third snapshot or clones for fs & volume again. |
| # 5. Roll back to the first snapshot and check the results. |
| # 6. Separately create two snapshots for fs & volume. |
| # 7. Roll back to the first snapshot and check the results. |
