Just now I reconfigured cluster suite in my machine and cman started without any error. I have followed the same steps that I have done earlier. This time I think that there is only problem GFS, which was not configured. I'm happy that CCS is working. However I will post the messages in /var/log/messages : Jan 3 14:46:58 triveni ccsd[7400]: Starting ccsd 1.0.0: Jan 3 14:46:58 triveni ccsd[7400]: Built: Jun 16 2005 10:45:39 Jan 3 14:46:58 triveni ccsd[7400]: Copyright (C) Red Hat, Inc. 2004 All rights reserved.
