I'm new to the list. This has possibly been discussed before, in which case a pointer would be welcome. We're planning a two-node heartbeat-controlled web server cluster possibly using DRBD to share the web sites' data between the two nodes. Some of the sites on this server are dynamically updated by users (eg, uploading photos or whatever), so it's important that both web servers can write to the shared data directories. Under consideration is using DRBD and making the primary accessible to the other web server by mounting it r/w via NFS. I realise that the NFS metadata will need to be on the DRBD volume, and that we need to get the appropriate services stopped/started if there is a failover, but in principle are there any problems with this? Is there any advice regarding NFS parameters for such a configuration? We'd rather use ext3 + NFS than one of the cluster filesystems and a master-master configuration, but if there are better ways of running a two node webserver cluster where either node can update the data then we'd like to consider them. Thanks for any help - K.
