Ubuntu – Mount LVM partition from Ubuntu LiveCD/ISO

live-cdlvmUbuntu

I have an old Ubuntu server inside a Virtual Box. I migrated to a new laptop a while ago and now for whatever reason I can't remember the password nor ssh to the box.

Ordinarily I'd fire up a Live CD mount the appropriate partition and fix the problems that way. The problem is this box is on an LVM. The LiveCD doesn't seem to have lvm2 which is allegedly what I'll need to get the partition mounted.

I've tried up to 14.04 and no luck. Is there a way to pull this off with an Ubuntu disk or maybe a third party LiveCD/ISO?

Boot from fedora live cd or somesuch, run

vgchange -a y

if the volume groups are not visible already, and the volume groups logical volumes will appear for you to mount

In theory, you could reduce the size of sda1, increase the size of the extended partition, shift the contents of the extended partition down, then increase the size of the PV on the extended partition and you'd have the extra room. However, the number of possible things that can go wrong there is just astronomical, so I'd recommend either buying a second hard drive (and possibly transferring everything onto it in a more sensible layout, then repartitioning your current drive better) or just making some bind mounts of various bits and pieces out of /home into / to free up a bit more space.
