22 # Description:
23 # Verify that nopwrite still works for a dataset that becomes a clone via
24 # promotion.
25 #
26 # Strategy:
27 # 1. Create a clone suitable for nopwrite.
28 # 2. Disable compression and checksum on the clone, and promote it.
29 # 3. Overwrite the file in the clone (former origin fs) and verify it
30 # consumes no additional space.
