| # DESCRIPTION: |
| # Verify that rollbacks are with respect to the latest snapshot. |
| # |
| # STRATEGY: |
| # 1. Empty a file system |
| # 2. Populate the file system |
| # 3. Take a snapshot of the file system |
| # 4. Add new files to the file system |
| # 5. Take a snapshot |
| # 6. Remove the original files |
| # 7. Perform a rollback |
| # 8. Verify the latest snapshot and file system agree |
| # |
