[Pacemaker] HA across WDM Fibre link - Nodes won't rejoin after reboot

[Darren.Mansell at opengi.co.uk]

Hi everyone.

 

I have 2 nodes running on ESX hosts in 2 geographically diverse data
centres. The link between them is a DWDM fibre link which is the only
thing I can think of as being the cause of this.

 

SLES 11 SP1 with HAE. All latest updates.

 

If Corosync is set to Multicast on the default address, there are no
comms between Corosync on the nodes. If I use broadcast, it will
communicate and let the nodes join.

 

If I reboot node 2, it rejoins fine. If I reboot node 1, it enters a
pending phase for a while then just drops to offline. I can then clear
the config out again and let the nodes rejoin. Node 1 always seems to be
the DC.

 

Pending - logs from node 1, loops this every second:

Any ideas please?

 

Thanks.
