LVM on LUKS: volumes missing

Hi, maybe I'm too shocked but I couldn't find anything on this issue :)

I have a fully encrypted HD using the LVM on LUKS method from ArchWiki[^0], with the LUKS header and key file on an external device.

Today I started having some disk failures (root remounted ro, xfs partition giving errors), and after I decided to reboot to run fsck, I can't find anything.

When the encrypted partition is opened, I don't see any errors, not even on dmesg, but LVM can't find any volume. They're just missing.

Is there anything I can do? Thanks!
