My proxmox host disk broken down, cannot boot, but can access on read only

[wepx]

Hi, yesterday my proxmox host disk are broken down, seems like a bad sector on the boot partition. it cant boot anymore but I still can access the file inside from another machine.
Luckily I saves all of my VM disk on another disk, so this disk only contains the proxmox host OS. I have backup but seems it is on the same disk (host OS disk), but not all is backed up..

I did reinstall proxmox on new SSD but I lost all of my VM config..
is there anyway to restore the VMs from the previous disk?

Mount your old disk "/" eg. to /net, then sqlite3 /net/var/lib/pve-cluster/config.db .dump > ~/oldpve.dump
Maybe you need /net/etc/network/* for restore sdn networks also.

Another possibility, install a new proxmox host on a new disk, connect the damaged disk afterwards to the new host, mount it and copy the VM's to your new disk, config files can be found in /etc/pve/qemu-server
