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? -- Dipl.-Inf. Timo Schaepe (Projekt- u.
