corosync [TOTEM ] Retransmit List: 1

[tapsa]

We have problem that cluster show nodes as offline.
To /var/log/cluster/corosync.log flooding corosync [TOTEM ] Retransmit List: 1

I find that this is known problem http://www.hastexo.com/resources/hints-and-kinks/whats-totem-retransmit-list-all-about-corosync
but on proxmox there is no corosync.conf

When I look with tcpdump it show this:
kvm10.localdomain.5404 > 239.192.104.2.5405: UDP, length 1571

So looks that corosync try send 1571 bytes packet even mtu is 1500

Any ideas howto fix this?

Not sure if this will help but hopefully this points you in the right direction.

There are some notes I added to the wiki here that mention how to set the MTU for totem.
I've not tested this, and it is not as simple as editing the cluster.conf directly

The procedure for making changes to cluster.conf can be found here:

Hi,

I have the same problem here (a cluster of 11 different powerful node). After a while, nodes will be shown as not reachable.

@tapsa: Could you solve the problem?
