[SOLVED] Joining a 3rd node in cluster fails

[nemo123]

Hello all I am new to networking so I might made something wrong, but I am not sure where the problem is. So I hope someone can help me through this.I could not find any solution for this on any other articles.

Somehow I am not able to add the 3rd node for my HA cluster.
Preliminary information:
1.) I didn't set up my available switch maybe I should?
2.) PVE 6.4-15 on all 3 Nodes
3.) I also tried to add them via shell


This is how my Network setup is right now



So as it is to see I have on my 3rd node just 2 ethernet ports someohow people manage to get 3 nodes with only one ethernet port?
Btw. this one below is not mine setup, it is just another one in the video to see at 7:49.



However this is my network setup on the pve1:

And almost simular to it the pve2:

So as you can see I have two seperate networks for the clusters (I don't know I tried one network for both as seen here, but it didn't work for me)

This is the network configuration of my 3rd node:


This is my Cluster right now (I know some do not have Link1 addresses)



Finally if I am to join with the 3rd node I am forced (shown as red box) to link adresses wich I dont have setup:







All other tutorials from the links before (e.g. starting at 11:30) don't have this forcement, they have "IP resolved by node's hostname":



Thank you all in advance for your efforts.

Hey what you can do on your third host is add another IP to the same interface. You have to edit your /etc/network/interfaces config:

In this example I added a second IP to the one already configured by proxmox:

auto vmbr0
iface vmbr0 inet static
        address 192.168.18.21/20
        gateway 192.168.16.1
        bridge-ports ens18
        bridge-stp off
        bridge-fd 0

auto vmbr0:1
iface vmbr0:1 inet static
        address 10.10.138.20/24

You can either reboot or call ifup -a to get the IP set on the interface.

Hi and thank you for your reply.
I found out, that I was not able to ping from node 3 to the other cluster networks.
So my next step was to check out for the switch, which was disabling it.
Then I also added another address as you have shown so thank you very much, now all 3 nodes joined a cluster
