| # DESCRIPTION: |
| # Verify 'zfs send' drills holes appropriately when files are replaced |
| # |
| # STRATEGY: |
| # 1. Create dataset |
| # 2. Write block 0 in a bunch of files |
| # 3. Snapshot the dataset |
| # 4. Remove all the files and rewrite some files with just block 1 |
| # 5. Snapshot the dataset |
| # 6. Send both snapshots and receive them locally |
| # 7. diff the received dataset and the old datasets. |
| # 8. Repeat steps 1-7 above with pool that never had hole birth enabled. |
| # |
