I was using network-based tiebraker, and changing to broadcast heartbeating
solved the problem.

After doing some tests, I changed do disk-based heartbeating, although the GUI
warned me that IP-based heartbeating was recommended for a 2-node
configuration (I have 2 nodes).

Yes, we are also not sure about these supposed iSCSI / CS3 problem, but the
only references we encountered were those from the Bugzilla.

I'll surely take a loot at it! Thanks!

By the way, tell me if you think we should open a case on Red Hat support for
this.
