Problem description is here: <a href="http://ubuntuforums.org/showthread.php?t=2128504">http://ubuntuforums.org/showthread.php?t=2128504</a> I managed to retrieve the metadata of the volume group and the logical volumes underneath, but I did not succeed using vgcfgrestore successfully in order to regain access to my data. It seems I might have to try dmsetup, but I am afraid I might destroy my data if I use it. I have no experience with that program. If any of you has any idea or any experience with restoring lvm volumes or using dsetup, please help me! </body></html>
