  34 # DESCRIPTION:
  35 #   Verify file truncatation within nfs
  36 #
  37 # STRATEGY:
  38 #   Concurrently perform mulitiple file truncatation with different file size,
  39 #   block size, offset.
  40 #     1. Open a file
  41 #     2. Write random blocks in random places, and read them back
  42 #     3. Truncate the file
  43 #     4. Repeat above two steps
  44 #     5. Close the file.
  45 #
  46 #
  47 # TESTABILITY: explicit
  48 #
  49 # TEST_AUTOMATION_LEVEL: automated
