[ClusterLabs] two node cluster: do the nodes have to be in the same subnet ?

[T.J. Yang]

Thanks Miachel for the pointer Bernd's question.

I have a two nodes spread across two WANs.  Here is the verification that
udpu unicast is being used.

[root at pcmk1 ~]# grep transport /etc/corosync/corosync.conf
transport: udpu
[root at pcmk1 ~]#
