This kind of errors often indicates that your /etc/hosts or DNS is wrong an=
d pacemaker has a hard time to map hostnames and IPs, etc (not sure about t=
he internals there...)<br>
Get rid of the invalid nodes by editing the configuration; stop pacemaker; =
fix your resolutions and retry.<br>
<br>
In the entire process, I usually use FQDN in my cluster.conf file, and I ad=
d them and the corresponding ring IP in my /etc/hosts file on all nodes. I =
also use the same FQDN in my pacemaker configuration.<br>
<br>
Cheers<br>

=A0 =A0 =A0 =A0 Do I need to have a cross over cable between each node? Is =

<br>
<br>
=A0 =A0 Nop it doesn't.<br>
=A0 =A0 In your case, I'd check the network architecture and/or firewal=

=A0 =A0 regarding multicast. You probably either have wrong iptables and/or=

=A0 =A0 a switch dropping your multicast corosync ring(s).<br>
<br>
=A0 =A0 Also, please, as Andreas said: try to communicate with us in a more=
