  24 # DESCRIPTION:
  25 # Scrubs and self-healing should be able to repair data from additional
  26 # copies that may be stored.
  27 #
  28 #
  29 # STRATEGY:
  30 # 1. Create a dataset with copies=3
  31 # 2. Write a file to the dataset
  32 # 3. zinject errors into the first and second DVAs of that file
  33 # 4. Scrub and verify the scrub repaired all errors
  34 # 7. Read the file normally to check that self healing also works
  35 # 8. Remove the zinject handler
  36 # 9. Scrub again and confirm 0 bytes were scrubbed
  37 #
