| # |
| # DESCRIPTION: |
| # Rewind to checkpoint on a stressed pool. We basically try to |
| # fragment the pool before and after taking a checkpoint and |
| # see if zdb finds any checksum or other errors that imply that |
| # blocks from the checkpoint have been reused. |
| # |
| # STRATEGY: |
| # 1. Import pool that's slightly fragmented |
| # 2. Take checkpoint |
| # 3. Apply a destructive action and do more random writes |
| # 4. Run zdb on both current and checkpointed data and make |
| # sure that zdb returns with no errors |
| # 5. Rewind to checkpoint |
| # 6. Run zdb again |
