Proxmox: Rename a standalone node (hostname)

Update 2021-01-09

DO NOT USE THIS PROCEDURE FOR NOW AS ITS OUTDATED AND BREAKING THE CONFIG

Doing some cleanup and had to rename a nodename of an existing standalone Proxmox Server.

Found that it wasn’t too straight forward because it detected the old nodename and placed the vz underneath it.

So here is a simple way to rename the Proxmox Node.

Firstly the normal steps:

vi /etc/hosts
vi /etc/hostname

Replace the entries with your intended hostname.

You will now need to restart pve in order to create the new hostname in the system.

service pve-cluster restart

This should now create a new host entry in Proxmox and a new folder under

/etc/pve/nodes/[newhostname]

You now need to copy your old openvz data from the old folder to the new.

mv /etc/pve/nodes/[oldhostname]/openvz/* /etc/pve/nodes/[oldhostname]/openvz/

Example:

mv /etc/pve/nodes/proxmox-portable/openvz/* /etc/pve/nodes/proxmox-Xen/openvz/

I would advise to restart the Proxmox host in order to finish the renaming.
