lilo, syslinux, loadlin, etc  doesn't have the same whacky
problems/requirements/restricktions that grub imposes

lvm ...
        - good for growing your FS ... if you had 10 GB disk and is 100%
        full, than you can in theory, add another 40GB disk
        and you'd now have more space

lvm ...
        - what a pain in the butt ...
        if any of the disk dies.. you lose everything

-----------

original problem ... if your FS is 100% full .. redesign, rethink
how and where data is stored and why, and more importantly,
how you are gonna backup the data ... BEFORE you grow your FS
and if you can in fact back it up, you dont need to grow your FS
since the backup is already working and is probably bigger
such that you and replace the primary too-small system while 
working off backup

        - disks will always be 100% full, no matter how big your PetaByte
        system is ..
