If it was second disk, it can be without partition table, lvm does not
require it.

Never try to recover something when you are not sure if it was there ;-)

You can easily check - in guest, go to the /etc/lvm directory,
there should be metadata backups. Chekck them, there should be comment
which disk was there.

Can you paste some old metadata (_correct_ metadata, before disk disappeared)
to pastebin and send a link to it? Or directly to mail.

run "blkid -p <disk>" on it - what it reports?

Why? These tries can do more damages. Maybe someone just installed
e.g. grub there - this is fully recoverable still.

Paste that metadata above, we will see.
