I've just finished putting together a basic Lustre cluster in a lab 
using DRBD for redundancy and heartbeat for failover on both MDS and 
OSS.  Failover is working fine on both.  We're using mostly commodity 
hardware.  So far the setup seems like a solid candidate for a very 
cost-efficient way of bringing redundancy and high-availability to 
Lustre.  In the coming weeks  we'll be growing the cluster as we do 
benchmarking and hopefully have something to add to the DRBD section of 
the Lustre  wiki(which is pretty thin ATM)
