[Pacemaker] WARN: Rexmit of seq ..........

[Joseph, Lester]

Yes they can. That's the confusing bit....

As I mentioned in previous email, we rebooted the switch and the nodes would have lost connectivity briefly. But the switch is back online now and the nodes have connectivity as they did before. Yet the message is constantly being generated despite my actions.

I will continue to troubleshoot.

Thanks.
The nodes in question are Virtual machines. Interestingly, we had a maintenance window this morning to restart the switches on the bladecenter serving this cluster.

Do I have to reboot the VM's to resolve this. This is only beeing seen on one of the nodes. I have already put this node in standby, stopped heartbeat service, deleted contents of /var/lib/heartbeat/crm and started heartbeat again. This is still being generated.

You say you restarted heartbeat... can both sides see one another?
Ie. in crm_mon

It looks like a network failure of some kind.

Switch going bad?
Not sure, I don't use heartbeat much these days.

Hi,
Not sure if this has already mean addressed in this list....apologies if it has.
Noticed a similar thread here http://www.gossamer-threads.com/lists/linuxha/dev/32877?do=post_view_threaded.
But no viable solution.

In a two node cluster, which has been working fine for months now, I am now getting loads of the following messages in the logs

Mar 24 09:13:29 bkglpapp06 last message repeated 7 times

Can you advise?
