23 # Description:
24 # Verify that if the checksum on the origin and clone is sha256, any compression
25 # algorithm enables nopwrite.
26 #
27 # Strategy:
28 # 1. Create an origin dataset with compression and sha256 checksum.
29 # 2. Write a 64M file into the origin dataset.
30 # 3. For each of 4 randomly chosen compression types:
31 # 3a. Create a snap and clone (inheriting the checksum property) of the origin.
32 # 3b. Apply the compression property to the clone.
33 # 3c. Write the same 64M of data into the file that exists in the clone.
34 # 3d. Verify that no new space was consumed.
