[SOLVED] Unable to join cluster "it must be configured exactly once on local node!"

[Giovanni]

I'm trying to troubleshoot a mistake I probably created during installing proxmox. I had selected DHCP during install and one of my two nodes received 192.168.255.111 IP.

I then later modified the /etc/network/interface file manually then rebooted, all seems when except when I try to join the cluster I just setup I get the following error:

local node address: cannot use IP '192.168.255.111', it must be configured exactly once on local node!

here is master node (first node):

Hi,

if you change /etc/network/interfaces
you have also change the IP in the /etc/hosts

Thank you, that's the one file I forgot about!
