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).
