Hi everyone,

Months ago, I got my Proxmox server installed with a default hosting provider hostname, thus used as node name.

I'd like to rename it, and procedures I found online do not work with Proxmox 4. When trying to copy /etc/pve/nodes/<old-node> to /etc/pve/nodes/<new-node> (either with a cp, mv, rsync), I have errors like 'lxc/101.conf file already exists'.

I guess this is about /etc/pve not being a regular folder? How to rename properly my Proxmox node without reinstalling? :)

Thanks!
 
Hi,

you must not reinstall your complete node. You only have to change your hostname in /etc/hostname and /etc/hosts.
Then restart your server. While restarting proxmox should create a new directory with your new hostname /etc/pve/nodes/.
Now you have to move all vm configs from the old folder into the new one.
For example: mv /etc/pve/nodes/<old-node>/lxc /etc/pve/nodes/<new-node>/lxc
 
@VoltStrecker: I did exactly like you stated.
1. Chnaged the hostname. Rebooted.
2. Got following error when I tried to copy the config for nodes:

root@server2:~# mv /etc/pve/nodes/ns2/lxc /etc/pve/nodes/server2/lxc
mv: cannot move ‘/etc/pve/nodes/ns2/lxc’ to ‘/etc/pve/nodes/server2/lxc/lxc’: Directory not empty
[Exit 1]

3. But the directory has nothing in it:

root@server2:~# ls -la /etc/pve/nodes/server2/lxc/
total 0
drwxr-xr-x 2 root www-data 0 Feb 3 19:48 ./
drwxr-xr-x 2 root www-data 0 Feb 19 09:30 ../

4. However, I tried to delete everything forcefully:

root@server2:~# rm -rf /etc/pve/nodes/server2/lxc

5. Yet, the command as in 1 works:
root@server2:~# mv /etc/pve/nodes/ns2/lxc /etc/pve/nodes/server2/
mv: cannot move ‘/etc/pve/nodes/ns2/lxc’ to ‘/etc/pve/nodes/server2/lxc’: Directory not empty
[Exit 1]

Is there anything else that one needs to do to copy the configs for nodes? Thanks!
