Pacemaker is the Cluster Resource Manager, so it doesn't really care about
the underlying method that the Messaging and Membership layer uses to
connect between nodes.

I've had this issue (crm_mon not connecting) when I performed an upgrade
from openais-0.80 to corosync-1.3.0 with udpu, I solved it by eventually
rebooting the servers. In your case I doubt it's an upgrade between versions
of software, since you've reinstalled.

My 2 cents.
