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 />
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 />
