one breakpoint would be if the heartbeat broadcasts grow in size as more nodes are part of the cluster, when that message grows from fitting in one packet to requireing multiple packets the reliability of the heartbeat drops drasticly.

I haven't looked at the heartbeat protocol in enough detail to know if this would be a factor or not.

Hi,
I wonder what is for now the *real* limit in the number
of nodes in a HA cluster with Pacemaker/OpenAIS ?
(not theoritical limit but a real one)

Thanks
