load balancing and shared filesystems

Right, that's it. I give up. Help me!

I am setting up a load balanced web 'cluster'. The idea of which is that if a single server fails, it will cause no downtime, and the slack will be taken up by the remaining servers.

I can load balance web traffic, I can cluster MySQL, I can deal with the possible PHP session problems.

I _cannot_ see an easy way to deal with the shared storage problem.

Having an NFS backend is all very well until it breaks.

I guess what I am really asking is how to provide a clustered NFS system whereby if one of the NFS servers goes down, the other continues serving content. How do you deal with the inconsistent data problem?

Argh! load balancing and shared filesystems
