Mount an LVM volume in Debian Live CD

I am covering how to mount an LVM volume within in a Debian Live CD.

I am covering how to mount an LVM volume within in a Debian Live CD.

I found myself in need of mounting an LVM environment inside of a Debian Live CD. It was not too terribly difficult, just not well documented anywhere.

The first step is to install LVM2.

sudo apt update;
sudo apt install lvm2

Next we need to get the name of the volume group

sudo pvs

That should dump out something like this:

  PV         VG               Fmt  Attr PSize    PFree
  /dev/sdb1  counterstrike-vg lvm2 a--  <126.26g    0

The name of my volume group is counterstrike-vg.

Now that we have the name of the volume group, in this case it is counterstrike-vg, we need to activate it. In the following command you need to replace counterstrike-vg with the name of your volume group.

sudo lvm vgchange -ay counterstrike-vg

If all went well that command should have put something out that looks like this

  2 logical volume(s) in volume group "counterstrike-vg" now active

You should now be able to see your drives in /dev/mapper, just as they should be. And can be mounted normally by using

sudo mount /dev/mapper/counterstrike--vg-root /mnt

Conclusion

I found a number of posts on how to do this, but none was complete. Now there is one that explains it.
