When you change your hostname or ip on a proxmox host it can happend that you’re unable to access the ui. Journalctl will throw errors at you like this
/etc/pve/local/pve-ssl.key: failed to load local private key (key_file or key) at /usr/share/perl5/PVE/APIServer/AnyEvent.pm line 1899.
When you try to interact with the qm commands or update the certificates it will show the following
ipcc_send_rec failed: Connection refused ipcc_send_rec failed: Connection refused ipcc_send_rec failed: Connection refused
To fix this make sure you changed your hostname with the command
hostnamectl set-hostname $YOURHOSTNAME
After this you need to change the hostname also at /etc/hosts. Make sure to set the hostname like the schema to new ip or hostname.
127.0.0.1 localhost.localdomain localhost your.new.ip.address your.fully.qualified.domainname yourhostname
Now you need to replace the old hostname in the storage-config, othervise you’ll not be able to see/use the old pool.
Keep the structure of the file, just replace the old hostname. You can do this like this in vim
or directly in the directory:
grep -rl "[oldhostname]" | xargs sed -i 's,[oldhostname],[newhostname],g'
After this you can restart all pve-daemons and the pools should be available
service pvedaemon restart service pvestatd restart service pveproxy restart
