| # DESCRIPTION: |
| # dRAID should provide redundancy |
| # |
| # STRATEGY: |
| # 1. Create block device files for the test draid pool |
| # 2. For each parity value [1..3] |
| # - create draid pool |
| # - fill it with some directories/files |
| # - verify self-healing by overwriting devices |
| # - verify resilver by replacing devices |
| # - verify scrub by zeroing devices |
| # - destroy the draid pool |
