Cluster network in Hetzner

[salva_alc]

Hi,

I'm trying to setup a Proxmox Cluster in Hetzner (1 public IP per node) and have a shared network in the cluster so if a VM/CT goes down in one node it can be started in the other without downtime. The CT/VMs should have internet access and be reachable from the internet (I'm ok with iptables)
DHCP, DNS, etc should be in this network

I also have a vSwitch for Cluster communications (corosync) which works great between the nodes



Any ideas?

Thanks in advance!

You might want to set up a third device for quorum https://pve.proxmox.com/pve-docs/chapter-pvecm.html#_supported_setups

Thank for the information Dominic.
I did not mentioned that I'm going to add a third node for quorum because that's not the problem I have.
My main problem is how to create and manage the same network with internet access in the cluster

Hello,

I'm trying to accomplish the same thing but even tho my cluster is working I have an issue, when my VM's try to communicate with each other it only works if they are on the same host, VM's on separate hosts can't reach each other :| Have you found a way around this?

if u want more details here is my original post: https://forum.proxmox.com/threads/vms-not-reachable-when-in-different-nodes.90761/
