Hi I playing with clustering bind. The named service has it's own IP resource. I have successfully tested a basic caching name servers all seems to be working. Now is it possible (or wise) to give the nodes of the cluster hosting the DNS service the resource IP as their DNS server in their resolv.conf. This is mainly so that other services can have a highly available DNS service. Multiple DNS servers in resolv.conf really is a non-starter as it takes forever to give up on the first name server and try the next one (then it always keeps trying the first server again on subsequent queries). My main issue, I think, is that I'm guessing so long as all my cluster node names (and any other names) used in cluster.conf are in /etc/hosts then the cluster suite itself should be happy ? Does is ever need to hit DNS? But what if services (maybe Samba or httpd) uses and/or requires DNS? I know I could make these dependant on DNS but that seems a bit messy (with so many services inside one). Plus I would like DNS to be in a different failover domain from some of the services. So I suppose the question is, does rgmanager start the service and decide a service is alive or dead based on just return status, not timeouts ? Will it get upset by a slow starting service? And will it start services in parallel (not waiting for each to start in turn)? Anyone else tried this?
