  31 # DESCRIPTION:
  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.
  37 #
  38 # STRATEGY:
  39 # Test 1
  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.
  44 # 5. Clear the pool
  45 #
  46 # Test 2
  47 # 6. For each checksum:
  48 # 7.    Create a file using the checksum
  49 # 8.    Corrupt all level 0 blocks in the file
  50 # 9.    Scrub the pool
  51 # 10.   Verify that there are checksum errors
