Hi guys and girlsI 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.
Working cluster schema: 5 Proxmox nodes, 1 x 10G switch, 1 x 1G switch.
Multicast ping (ssmping utility) working in direction: pve15 (on Extreme Summit switch) -> pve153 (on DELL switch) but not working on opposite direction (from DELL switch to Extreme Summit) random server (on DELL switch) -> pve153(on DELL switch) 10G Switches (connected to eachother, not stacked): Extreme Summit X670-48x DELL N4064F 1G switch: NetGear Servers - different DELL productsDoes 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.
All the best Sten Aus
