   6 Run the ctdb_bench test and sanity check the output.
   7
   8 This doesn't test for performance regressions or similarly anything
   9 useful.  Only vague sanity checking of results is done.
  10
  11 Prerequisites:
  12
  13 * An active CTDB cluster with at least 2 active nodes.
  14
  15 Steps:
  16
  17 1. Verify that the status on all of the ctdb nodes is 'OK'.
  18 2. Run ctdb_bench on all nodes with default options.
  19 3. Ensure that the number of +ve and -ive messages are within 1% of
  20    each other.
  21 4. Ensure that the number of messages per second is greater than 10.
  22
  23 Expected results:
  24
  25 * ctdb_bench runs without error and prints reasonable results.
