Doing this will make "lfs find" no faster than just using "find", so
it is fairly pointless.  Secondly, just using the file size is not
going to be accurate, because of sparse files.

I _think_ it is possible to enable Lustre quota w/o quota enforcement
(i.e. do not set any quota limits for users) and that would get you
what you want, but I'm not a Lustre quota expert and I could tell you
the commands to do this.
