- # Description:
- # Verify that duplicate writes to a clone are accounted as new data if the
- # prerequisites for nopwrite are not met.
- #
- # Scenarios:
- # 1. The file in the origin ds is written without compression or sha256.
- # 2. The file in the origin ds is written before sha256 checksum is turned on.
- # 3. The clone does not have compression.
- # 4. The clone does not have the appropriate checksum.
