Hello Steven,
Than what I see when setup through UDPU
Nov 23 22:08:13 corosync [MAIN ] Compatibility mode set to whitetank. Using V1
and V2 of the synchronization engine.
Nov 23 22:08:13 corosync [TOTEM ] adding new UDPU member {10.10.10.1}
Nov 23 22:08:16 corosync [MAIN ] Totem is unable to form a cluster because of
an operating system or network fault. The most common cause of this message is
that the local firewall is configured improperly.
Might be missing some firewall rules ? I allowed unicast.
Slava.

Hello Steven,
My setup

On both servers is 2 interfaces eth0 which default gw out and eth1 where

Is it possible that ping sends out of wrong interface ?
Slava,
I wouldn't expect so.
Which version?
Have you tried udpu instead? If not, it is preferable to multicast unless you
want absolute performance on cpg groups. In most cases the performance
difference is very small and not worth the trouble of setting up multicast in
your network.
Fabio had indicated rrp active mode is broken. I don't know the details, but
try passive RRP - it is actually better then active IMNSHO :)

This can occur because:
a) firewall is enabled - there should be something in the logs telling you to
properly configure the firewall
b) a config change is in progress - this is a normal response, and you should
try the request again
c) a bug in the synchronization code is resulting in a blocked unsynced cluster
c is very unlikely at this point.
2 ethernet interfaces = rrp mode, bonding, or something else?
Digimer needs moar infos :)
