LVM the gentoo way works fine: I highly recommend for any system needing multiple partitions
http://www.gentoo.org/doc/en/lvm2.xml After a disk failure (one of a two disk raid zero stripe), I added the new disk as LVM2, copied the files that I could salvage over and then did an emerge -e world to fix what was damaged/missing. The last step was to reclaim each of the partitions on the remaining good disk and add them to the LVM (actually I just fdisked it all into one big partition except swap. My file system sizes (reiserfs) have now changed a couple of times, the LVM now runs across both disks (200G and 60G). It took just 5 mins (mostly re-reading the docs) to add 12G to my /tmp when I ran out of space during a file conversion project - it was just so nice!
