I would try and avoid that if possible. It's much better to make sure that all
of the services are shut down beforehand and let cman shut down tidily.

Check for things like ccsd still running and services shown my 'cman_tool
services'. Unfortunately it can be hard to determine which cluster services are
running if you don't know what they all are, but it's worth trying  :-)
