As a status update, not got any further...
Confirmed with the Networks people that Multicast is enabled, but no luck.
Using unicast crm is not able to connect to the cluster (below is the unicast config used).
With unicast, there's no traffic at all (observed via tcpdump)
Beginning to wonder if there's either a version mismatch problem between those packages perhaps.
These are the package versions:
corosynclib-1.4.1-4.el6_2.1.x86_64
clusterlib-3.0.12.1-23.el6.x86_64
pacemaker-cluster-libs-1.1.6-3.el6.x86_64
resource-agents-3.9.2-7.el6.x86_64
cluster-glue-libs-1.0.5-2.el6.x86_64
pacemaker-libs-1.1.6-3.el6.x86_64
corosync-1.4.1-4.el6_2.1.x86_64
pacemaker-cli-1.1.6-3.el6.x86_64
cluster-glue-1.0.5-2.el6.x86_64
pacemaker-1.1.6-3.el6.x86_64
Between yesterday and today updated corosync from
1.4.1-4.el6 to 1.4.1-4.el6_2.1
No change however :|
OS is CentOS 6.2
Colleague's now compiling a few heartbeat packages instead to see if that gets the job done.
This being the config for unicast
compatibility: whitetank

}

logfile: /var/log/cluster/corosync.log
debug: on

logger_subsys {
subsys: AMF
debug: off
}
}
amf {

}
Any further ideas perhaps? Since I'm losing the plot myself somehow :(
Cheers!

Hi,
According to the network guy the multicast is all there, but we've got no step further, so we're trying your suggested method now :)
Didn't know that corosync now supports unicast too, must've missed that...
Thanks for the heads up!

Or use upnp ... unicasts if you don't want/can change your network setup
