Verify that 'ctdb getpid' works as expected.
Prerequisites:
* An active CTDB cluster with at least 2 active nodes.
Steps:
1. Verify that the status on all of the ctdb nodes is 'OK'.
2. Run 'ctdb getpid -n <number>' on the nodes to check the PID of the
ctdbd process.
3. Verify that the output is valid.
Expected results:
* 'ctdb getpid' shows valid output.
