Due to a change in the switch in one of the datacenters now I have an odd
behaviour in the cluster.
I am using cman with corosync and pacemaker. The versions are:
The problem is, when I launch /etc/init.d/pacemaker start and the cman_tool
launch corosync, I don't see any UDP traffic, so the cluster is "broken"
But if I launch manually the same command "corosync -f" I do see udp
traffic and the totem is correctly sent between nodes.
It all began with the change in the switch, but I set the tcpdump in the
hosts and I do not see traffic.
I have tried the multicast and unicast configuration, different network,
but all with the same behaviour.
What am I missing?
