   It has to reserve more space for the metadata structures, but most of   
   them are dynamically created when needed.   
      
   There are some disadvantages for a grown xfs system compared to one   
   created with the big size from the start. I don't remember which, but   
   some of the structures do not cope very well (with large size grown). I   
   read about it in the xfs mail list.
