Hi guys and girls<br>
<br>
I am adding new 10G switch (and connect two 10G switches) and
installed one new Proxmox node there. Multicast and spanning-tree
has been turned on on both switches. But I cannot get quorum between
this new node and existing nodes. I can see new node from the GUI
(red cross) and on the "pvecm nodes" output, but it won't attach to
cluster properly. Of course I can ping and ssh both directions.<br>
Working cluster schema: 5 Proxmox nodes, 1 x 10G switch, 1 x 1G
switch.<br>
<br>
Multicast ping (ssmping utility) working in direction:<br>
pve15 (on Extreme Summit switch) -> pve153 (on DELL switch)<br>
but not working on opposite direction (from DELL switch to Extreme
Summit)<br>
random server (on DELL switch) -> pve153(on DELL switch)<br>
<br>
10G Switches (connected to eachother, not stacked):<br>
<meta charset="utf-8">
Extreme Summit X670-48x<br>
DELL N4064F<br>
1G switch: NetGear<br>
Servers - different DELL products<br>
<br>
Does anyone have some suggestions on that? :) I am guessing
misconfiguration on DELL Switch, but hope to find any suggestions,
if someone has bumped onto this kind of problem.<br>
<br>
All the best<br>
Sten Aus<br>
