my proxmox web interface failed to start after reboot. i ran a systemctl status pveproxy.service and here is the log.

root@odc-host1:~# systemctl status pveproxy.service

seems your DNS-resolution or rather your /etc/hosts are not configured correctly

make sure that the hostname you've set resolves to an ip-address by adding it to /etc/hosts

hope this helps!

Ive got it back up but i was mesing arround with the name on the server and i cant get the vms back up

 

[Stoiko Ivanov]

Hm - I guess you renamed the host from 'pve' to 'odc-host1' ? (and that it's a single-node setup and not a cluster)

In that case the most likely cause of the problems is, that the clusterfilesystem (pmxcfs, mounted on '/etc/pve') still references the old hostname,
you need to move the directory from '/etc/pve/nodes/<oldname> to '/etc/pve/nodes/<newname>' - and restart some services (a reboot would be best, but you can try restarting 'pvestatd', 'pvedaemon' and 'pveproxy')

hope this helps!

Im getting this error when i try to move it.

mv: cannot move '/etc/pve/nodes/pve' to '/etc/pve/nodes/odc-host1/pve': Directory not empty
root@odc-host1:~#

 

[Stoiko Ivanov]

oh - I guess in that case - move every file in '/etc/pve/nodes/pve' to '/etc/pve/nodes/odc-host1/'
`mv /etc/pve/nodes/pve/* /etc/pve/nodes/odc-host1/`

I just changed the hostname back to pve and rebooted the whole server. seems to be working fine now. Never changing the hostname again . thanks for the help!!!!
