Proxmox OS disk failure - Restore old container on new disk

[robinjongeneel]

Hi there! I'm running a Proxmox 7.0 server. Unfortunately the disk where I kept my VMs, containers and Proxmox itself on failed. I didn't back up the VMs and LXC. I have only a backup of the Postgres server that was running in the LXC. Though the back up is 3 days old (not that problematic, but I hope to restore all data). I have some other disks on which I can continue, but I'd love to try to get the LXC from my old disk and I do not know if this is possible. I've searched around a lot but didn't find anything.



The failed disk is currently in read-only mode. I have added the volume and can see the VM disks.

I can recreate the VMs without problem. The only thing I'd love to restore is the container. Is there any way I can copy the filesystem or restore the LXC to my new disk and keep the data (assuming that the data is still intact).

hi,

do you have the configuration file for your container? or can you remember the ID for it?

if your old disk is still readable then you should be able to find your container volume in there, create a new container on the new disk and attach the volume to it (by editing the config file of the new container and moving the disk to the appropriate place in your new storage)
