The birthday paradox says that with a 44-bit hash we're more likely than not to start seeing collisions somewhere around 2^22 directory entries. That 16-million-entry-directory would have a lot of collisions. This is really the key point. The risks of the bit-stealing approach have been

An alternative would be to convert directories into regular files from the brick point of view. The benefits of this would be: * d_off would be controlled by gluster, so all bricks would have the same d_off and order. No need to use any d_off mapping or transformation. I don't think a
