   6 Verify that 'ctdb statisticsreset' works as expected.
   7
   8 This is pretty superficial.  It just checks that a few particular
   9 items reduce.
  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 statisticsreset' on all nodes and verify that it executes
  19    successfully.
  20
  21 Expected results:
  22
  23 * 'ctdb statisticsreset' executes successfully.
