Hi Martin, I might be missing something but I have set up a 2 node high availability cluster by having 2 servers defined in the same zone and having them both running a database locally. They are configured to talk to their local database only. The Icinga cluster protocol keeps the instances in sync which in turn update their local DB. I do need some sort of replication for things like the web interface users data base. You need to think about zones and how and where checks run though. This set up is working well for me at the minute (though the cluster node's aren't geographically dispersed and I don't mind if checks run from both servers. )
