The controller of my SSD (Samsung 980 Pro...) died so I have to rebuild my setup from backups. The first step is to install PVE and on top of that PBS and update everything, then do my LUKS setup on my external RAID and recover
The original setup is:
The server data (of the single VM I am currently using) lives on the RAID, and gets backed up to a LV on the internal SSD (as well as to the cloud). I have not lost server data, I lost the internal backup of server data, but I still have one external restic backup of server data on B2.
The VM itself lives on the internal SSD and gets backed up with PBS to the RAID. I lost that VM, but I have a PBS backup on the RAID.
I had:

I lost the internal SSD, so I lost my VM (which I should be able to restore from the PBS backup), the docker cache of the VM, and the restic backup of server data (of which I still have external backups).
Now, the bad news is that I probably have lost a
Basically, I need to recreate the LV thin VG and the LVs, but I recall that doing that from the command line did not work years ago when I first set it up (2022, PVE 7). What is my best way forward at this point?
