| # Description: |
| # Verify incremental receive properly handles objects with changed |
| # dnode slot count. |
| # |
| # Strategy: |
| # 1. Populate a dataset with 1k byte dnodes and snapshot |
| # 2. Remove objects, set dnodesize=legacy, and remount dataset so new objects |
| # get recycled numbers and formerly "interior" dnode slots get assigned |
| # to new objects |
| # 3. Remove objects, set dnodesize=2k, and remount dataset so new objects |
| # overlap with recently recycled and formerly "normal" dnode slots get |
| # assigned to new objects |
| # 4. Create an empty file and add xattrs to it to exercise reclaiming a |
| # dnode that requires more than 1 slot for its bonus buffer (Zol #7433) |
| # 5. Generate initial and incremental streams |
| # 6. Verify initial and incremental streams can be received |
| # |
