What versions of corosync and pacemaker do you have on node 3? What
version of corosync is on nodes 1 and 2?

This is a normal message, it means the node doesn't have STONITH, this
happens because it can't see the rest of the cluster (which would also
mean it would get the cluster config from the other nodes).

Between Fedora 13 and RHEL 6 it may or may not work, so the answer
would be, it depends. Best thing for a rolling upgrade would be to put
the cluster in maintenance-mode, upgrade all software, make sure it
works, refresh, reprobe, and if all is ok, take the cluster out of
maintenance mode.
