ext2 to ext3 requires no reformatting. You umount the volume, run
tune2fs -j /dev/whatever
and then mount it as ext3.
I don't think similar tools exist for reiserfs (ext3 is ext2 with a journal
reiserfs is a fundamentally different fs design so its obviously much much
harder to write in place convertors)
