Thanks Fabio for your clear explanation.

I was thinking about this upgrade just to see if the "two nodes" case
was better handled.

Here first we had to add a quorum disk, and despite this, we were
still having some troubles when rebooting (done with a reboot command
from a shell):
rgmanager waiting forever while stopping, services not migrating to
the second node, fencing not starting when the other node is powered
off (clean_start="1" and power fencing)...

Adding a third node _seems_ to have solved most of them, though.
