I was working on my trusty and crusty (15 year old!) desktop Pyg which just got a recent Manjaro reinstall, when suddenly the LVM partitions disappeared. The only clue I had is that the 3 directories that I use to access the logical volumes started throwing Input/Output error. I rebooted and it went straight to the recovery console (which is not a good place to be). I tried manually mounting the LVM partitions and it gave this error:
This was a bit of a shock and no reboot or safe mode can restore the directories. I put it off for the night and took it up again today. I was thinking maybe it was a recent Manjaro system in-place upgrade so I tried booting to the latest Ubuntu livecd (using Ventoy, which is very good for creating a multi-system bootable drive) hoping it will show up my lost LVM partitions.
I booted up to the Ubuntu live desktop and I didnt see any LVM mapper entries either. I see the same 800++GB unallocated space at the tail end of the SSD. I launched a filesystem check which didn’t reveal anything and started searching on how to manually input the the LVM sectors in the GPT metadata.
I searched my Google keep for Pyg’s partition layout and then it hit me that all I am seeing is the SSD. There is a WD Blue mechanical drive in this machine before I upgraded to SSD and I used that for storage for files before they are backed up to either DVD or BlueRay. I checked the BIOS of the desktop and it confimred that the HDD is not showing up. Opening up Pyg seems to be my next weekend project.
Curiously enough, I am not feeling as much worry on losing the files as I remember the first time that my WD Green drive malfunctioned. Maybe those files in the LVM partitions (warehouse [files], limbo [multimedia] and arena [game files[) are really not worth that much in the grand scheme of things. If I can still recover them then thats fine but if not then…
