   6 Verify the operation of 'ctdb isnotrecmaster'.
   7
   8 Prerequisites:
   9
  10 * An active CTDB cluster with at least 2 active nodes.
  11
  12 Steps:
  13
  14 1. Verify that the status on all of the ctdb nodes is 'OK'.
  15 2. Run 'ctdb isnotrecmaster' on each node.
  16
  17 3. Verify that only 1 node shows the output 'This node is the
  18    recmaster' and all the other nodes show the output 'This node is
  19    not the recmaster'.
  20
  21 Expected results:
  22
  23 * 'ctdb isnotrecmaster' shows the correct output.
