How do I move a raw disk image from LVM-thin?

[BigBulb]

I encountered an error trying to start one of my containers; the error had something to do with space shortage on the container which I didn't understand because there should've been enough space for that container and there weren't that much things on it, so I tried deleting that container so that I could restore it from my backup. When I restored it, I found that the data I had on a pair of separate mirrored disks were gone. On those mirrored disks, I had a disk raw file with some data, but it looked like that the raw image that I need was moved to LVM-thin and I don't know how to move them back.

The Proxmox system is installed on a 120gb SSD and the mirrored drives are 2x4tb hard disks. The LVM-thin is 52.98 GB and the usage of that space is 100% because that raw disk image is more than that capacity. The disk image was meant to be in a storage directory on the mirrored disk, but that directory is empty and shows 0 space usage, but the image of 4tb size is in the vm disks tab. On the CT volumes in the LVM-thin tab, there's a disk image of 2.93TIB which should be the thing I want to move back. I'm new to all this and I obviously did things the wrong way somewhere.

Check what's mounted:
lsblk -f

Then what your storages point at:
cat /etc/pve/storage.cfg

If the mirror is unmounted, your data is intact and this is a mount fix rather than a recovery job.

I added the mirrored drives to fstab to mount automatically, so they would be mounted.

Local-lvm doesn't have a path like the others on the list after using the cat command

lvmthin: local-lvm
        thinpool data
        vgname pve
        content images,rootdir
