Hi Bruno, I am quite new to the redhat cluster suite myself but I will try to explain. Detecting whether the cluster has failed will depend on how many nodes you have setup and how you have configured them. I would suggest reading up more on quoroms and failover domains in the documentation which will explain better than I would. With regards to individual service on a cluster, the script that is called to start the service if it is a software service will be called with a status parameter which will tell the cluster whether it is in good condition or not. There is more customizable fields in these scripts in embedded xml files( it would probably have been more logical to put them in a conf directory...) that can be customized. The scripts I am talking about is the standard scripts that come with the cluster software and can be found in: /usr/share/cluster I hope this helps.
