Hello,
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:
pacemaker-1.1.10-14.el6_5.3.x86_64
corosync-1.4.1-15.el6_4.1.x86_64
cman-3.0.12.1-49.el6.x86_64
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?
I'm pretty sure main problem is that:
- corosync -f uses /etc/corosync/corosync.conf as a config file
- cman_tool join uses /etc/cluster/cluster.conf as a config file
Make sure to "replicate" (specially udpu/udp, ...) configuration from
corosync.conf to cluster.conf and I'm pretty sure it will work.
Regards,
Honza
Best Regards
