Mounting an old LVM volume on Ubuntu 20.04, is very easy, there are numerous posts on Stackoverflow that have many complicated commands for mounting a drive using the command line. But I needed to mount an old Ubuntu installation and it was an LVM2 volume, so I could not get it to mount on Ubuntu 20.04. But then I found out that if you use this simple command, and install the LVM2 system, then the drive will be mountable in the Caja file manager upon a reboot.

Better than some answers that were telling a person to format the drive before mounting it! Here it is: https://askubuntu.com/questions/766048/mount-unknown-filesystem-type-lvm2-member/872130#872130. But all you need is the LVM2 system installed and it is very easy. Get information about your LVM2 volume groups with this command.

The drive UUID may be used as an identifier to rename the volume group.

This shows how easy it is to work with an LVM2 volume group. It is easy to mount them on Ubuntu. Just use the proper drivers and this is very simple.
