Probably you're thinking of layering a unionfs over the top. It works well in my experience.

I believe that Sun's ZFS works in a similar fashion to this. It's a combined File System and Volume Manager that aims to make (and in my experience succeeds in making) disk storage handling as transparent as memory storage handling. It's available for the BSDs, Mac OS X has Read Support for it, but as far as I am aware it's still only available as a User-Space (FUSE) system on Linux. DBW
