I set up a pair of test servers with this running - with a view to 
moving to production at some stage in the future. DRBD seems to work 
well although I didn't do any detailed performance testing.

Note that DRBD can only be accessed on one node at a time (the so called 
active node) so it may not be suitable if you want all of your 
fileservers serving requests simultaneously. Also, for automatic 
failover between your primary and secondary nodes, you'll need to 
configure up some HA framework (either the older, apparently deprecated 
heartbeat http://www.linux-ha.org/ or the moving target that is 
corosync/pacemaker - http://www.openais.org) which is non-trivial.

If you want a generic filesystem replication solution, you could also 
look into http://www.gluster.org/,http://www.xtreemfs.org/ or 
http://oss.oracle.com/projects/ocfs2/ as some possible candidates).
