32 # Sanity test to make sure checksum algorithms work.
33 # For each checksum, create a file in the pool using that checksum. Verify
34 # that there are no checksum errors. Next, for each checksum, create a single
35 # file in the pool using that checksum, corrupt the file, and verify that we
36 # correctly catch the checksum errors.
40 # 1. Create a mirrored pool
41 # 2. Create a file using each checksum
42 # 3. Export/import/scrub the pool
43 # 4. Verify there's no checksum errors.
47 # 6. For each checksum:
48 # 7. Create a file using the checksum
49 # 8. Corrupt all level 0 blocks in the file
51 # 10. Verify that there are checksum errors
