VM backup when root is disabled

[jlambo]

Hi
I'm new to proxmox as is my team, the previous guy who set this up has left the company so please bear with me for any basic questions.

We have had some issues with our NMS system running out of space and we expanded/resized the volume but we found the previous guy had disabled root access and used another user account, we got around this issue and everything seemed fine.

I am now trying to figure out why my tmp folder maxed out alongside some minor issues with have happened since the resize and reboot.
I created a backup before the volume was expanded and the VM was restarted but only seem to have the option to log in as root from the console, but as this had been disabled it kicks me out instantly, is there anyway round this? I have tripled checked the passwords and ensured there isnt an issue with special characters etc...

Any advice would be great if there is a way not to log in as root from a backup VM just via console available through proxmox

is this a lxc container or a vm? if it is a container, do

pct mount CTID

chroot /var/lib/lxc/CTID/rootfs

Now you are inside the containers filesystem, set new password by

passwd root
NEW PASSWORD
NEW PASSWORD

check that root shell is set to /bin/bash and not /bin/false or something like that

getent passwd root
root:x:0:0:root:/root:/bin/bash

exit chroot with

exit

if it is a vm boot the vm with a live iso (eg ubuntu), mount the filesystem of your vm ond continue like above.
