Hi Alfredo,

If you've got a live CD, boot it up and execute the following commands:

[root at archiso]# modprobe dm-mod
[root at archiso]# vgscan
  Reading all physical volumes.  This may take a while...
  Found volume group "YourVolGroup" using metadata type lvm2
[root at archiso]# vgchange -ay
  NUM logical volume(s) in volume group "YourVolGroup" now active
[root at archiso]# lvdisplay
<useful content for you goes here>

It should be possible from a serial console, too, if you can execute
and /sbin/lvm from there. Prefix vg- and lv- commands with /sbin/lvm.

Yours sincerely,
