| # DESCRIPTION: |
| # Create two files of exactly the same size. One with compression |
| # and one without. Ensure the compressed file is smaller. |
| # |
| # STRATEGY: |
| # Use "zfs set" to turn on compression and create files before |
| # and after the set call. The compressed file should be smaller. |
