[all variants] Server Upgrade fails due to LVM missalignment

view story

http://ubuntuforums.org – I have a small intel atom server running ubuntu server 11.10. Upon installation I allocated the entire disk (2TB) to LVM using the standard partitioning scheme (boot, swap, root, data). So far so good. Unfortunately I can't upgrade to any recent versions because newer versions of Grub don't fit in the disk space that precedes the LVM. This has been documented in long and broad. I have made several attempts to upgrade but each of them failed and leave met with a none working grub although the rest seems to be fine. After reinstalling the original system everything is working again as it was. (Hardware)
