It was easy for me to work with CTS. I read about the basics of CTS in
the book of Michael Schwartzkopff (Clusterbau). Some deeper information
about the configuration I got from the README and that was enough to
start some tests.

What I missed is a short explanation of the tests and the meaning of
their failures. For example my cluster fails completly at the
ResourceRecover and Reattach tests. But unfortunately I only know the
meaning of the ResourceRecover test, because there is an explanation in
the Schwartzkopff book. Maybe there is an online resource that I had
overlooked till now.

And I am not sure, how I can test a cluster with STONITH resources with
the CTS. Should I use the stonith-ssh?
