Help! I messed up my PVE by changing the hostname.

Hi.
I was trying to change the hostname, by editing /etc/hostname and /etc/hosts following the guide from the wiki.
It didn't work as I found 2 different nodes into the Web UI, then I moved all the content from the old node folder in /etc/pve/nodes to the new one (this includes lxc, qemu-server, config and other folders)
I restarted the node and I suddenly got my /etc/pve erased.

Here's the output of journalctl -u pve-cluster

Code:

Hi,

First, make a backup for config.db file then try to edit it and remove duplicated values.


Hope that helps

Hi. I solved by extracting the VZ images from the disk and reinstalled the node to a new SSD.
But, I lost a .raw image of a CT. Is there any way to recover it if it was deleted?
 
Made an account to say I just got hit by this exact same bug.

Had just got my network setup the way I wanted it. Multi country, several proxmox and pfsense nodes, the whole shebang. all to be undone by changing a hostname. It has been a very long day indeed.
