| # DESCRIPTION: | ||
| # Test that receiving a full send as a clone works correctly. | ||
| # | ||
| # STRATEGY: | ||
| # 1. Create pool and filesystems. | ||
| # 2. Send filesystem, receive as clone of itself. | ||
| # 3. Verify that nop-write saves space. | ||
| # 4. Send filesystem, receive as clone of other filesystem. | ||
| # 5. Verify that contents are correct. | ||
| # 6. Repeat steps 4 and 5 with filesystems swapped. | ||
| # | ||
