   6 Verify that 'ctdb process-exists' shows correct information.
   7
   8 The implementation is creative about how it gets PIDs for existing and
   9 non-existing processes.
  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. On one of the cluster nodes, get the PID of a ctdb client.
  19 3. Run 'ctdb process-exists <pid>' on the node and verify that the
  20    correct output is shown.
  21 4. Run 'ctdb process-exists <pid>' with a pid of ctdb daemon
  22    process and verify that the correct output is shown.
  23
  24 Expected results:
  25
  26 * 'ctdb process-exists' shows the correct output.
