  By default gnump3d runs with user=gnump3d.  If you say that you've
 changed that to 'user=maurao' and that fails then I'm going to guess
 that it is an issue of the *primary group* of the user which is
 causing problems.

  From memory the code, when started by root, tries to change to
 the primary group of the user - then the actual user.  So if the
 primary group of 'gnump3d' is 'gnump3d', or something else, then
 this will fail.

  Simplest suggestion is to change the primary group.

  If that fails then run:

    su - gnump3d

  Then show us the output of :

    ls -l /mnt/data/
    cd /mnt/data && ls -l |  head
