Put LVM on top? You could create LVM on the new array, copy your files over, then extend. If you know LVM _really_ well, it's also possible to convert existing filesystems without moving data (other than relocating the parts occupied/unusable by LVM, i.e. one extent-size worth of data at start and end of disk). Or find a way to use more than one filesystem. > And there is also question of spare drive.
