| # DESCRIPTION: |
| # Create a snapshot from regular filesystem, volume, |
| # or filesystem upon volume, Build a clone file system |
| # from the snapshot and verify new files can be written. |
| # |
| # STRATEGY: |
| # 1. Create snapshot use 3 combination: |
| # - Regular filesystem |
| # - Regular volume |
| # - Filesystem upon volume |
| # 2. Clone a new file system from the snapshot |
| # 3. Verify the cloned file system is writable |
| # |

| # Setup array, 4 elements as a group, refer to: |
| # i+0: name of a snapshot |
| # i+1: mountpoint of the snapshot |
| # i+2: clone created from the snapshot |
| # i+3: mountpoint of the clone |
