Are you using disk-based or network-based tiebreaker?

I was never convinced that this was an iSCSI / RHCS3 interaction
problem, for what it's worth ;)

There shouldn't be, but if there is, it's due to a network / iSCSI
interaction problem that I do not really understand ;)

I wrote some stuff here about RHCS3 + network configuration here, so I
won't retype it.  Take a look and see if anything rings a bell with your
