As I told you, we used dumb Linksys switch for cluster communication and
it all worked for weekend and yesterday. And yesterday evening whole
cluster is red again

Maybe a problem with packet
9000 MTU is based only on storage VLANs, which use 10G interfaces.
All Proxmox cluster communication uses VLAN15, MTU1500.
Rebooted Linksys switch, no good. Swapped to another dumb switch without
VLANs - again no good.
cman restart in one node
*service cman restart*
Stopping cluster:
Hi,
Error is not lan, but kernel modules - reboot node and its fixed

Okay, back to zero.

Hi
Token timeout did not make anything better nor worse. :)
But now configured cluster VLAN directly to dumb Linksys switch (without
VLANs), using 1G interfaces. And it's working - adding and deleting new
and old nodes works like a charm.
Network department have also debuged this scenario
Everything is working good until I try to add a new node. As soon as I
do that, whole GUI breaks (KVM stays working, luckily) and all hell
breaks loose, as it's said.
So, we have eliminated network card issues - as this problem occurs with
different network cards. We have eliminated
Okay, I have now updated all nodes to same kernel versions. Thanks to
the bugfix with latest update, IPv6 now works with newer kernel as well.
So, all nodes are in the same version and packgages.
Anyway, now I cannot add no new node. Even I can't add this old node,
which was in the cluster
Tried another thing - removed existing node from cluster. Still no good
when adding new nodes. So eliminated new factor - it's not about limit?
no
