Proxmox Cluster IP update

[aussiexile]

Hi, I have tried to update the IPs of my cluster following various guides,

I updated the Interfaces, Hosts and corosync.conf.

None of that worked so I tried changing it back to the original IPs and now I can't access the console.

I rather foolishly started this without doing a back up.

My question is am I screwed and have to start from a fresh install?

I am rather new to proxmox so I am unsure of what info to include and where to find it so any help would be greatly appreciated.

Post your /etc/network/interfaces. And anything else changed.

I have included images (because I can't access the console to take screenshots) of 2 of the nodes.

The third is similar but I can't get images of them
