I just installed Manjaro on to a externalized usb hard drive. After I was done, I tried to boot from my previously working Mint distro (no full-disk luks) on my internal hard drive. The lvm volume groups had disappeared!?

I have switched the disks around and now the non-working disk is
I have read that there is meta data backup in
/etc/lvm which is of course inside
/dev/sdb5 and not
I would like to see a better answer for this.
If there is not a way to restore the disks then what are my options? Are these among them?
- Are there any forensics tools that can give access to the data?
- Another thing is the partition scheme was the standard linux Mint. If I reinstalled Mint could the new meta-data be used to try to recover the old?
