Depends on what you want to do - for instance:
Build a balanced server farm to handle a lot of traffic:
Just use a NFS server as centralized storage for your document root and
let all cluster-nodes access it. Your balancer(s) can handle the HA part
and manage your server-pool. Your NFS server is your SPOF though if it's
not a cluster itself.
Build a (two node) failover cluster:
Take a look at DRBD - it's a redundant network block device. You can use
almost any filesystem on top of it. Preferably journaling of course.
