  34 # DESCRIPTION:
  35 #   Looply create a large amount of dirs with large files until
  36 #   no space is available, the system should be stable.
  37 #
  38 # STRATEGY:
  39 #   - Looply create a large amount of dirs which include some files
  40 #     until the error occurs.
  41 #   - Verify the filesystem is full and system is stable
  42 #   - Remove all dirs and files
  43 #
  44 # TESTABILITY: explicit
  45 #
  46 # TEST_AUTOMATION_LEVEL: automated
