Defrag is only run when you are expanding existing subvolumes for 
distribute. Expansion has a caveat since the directories will not be 
distributed unless "scale-n-defrag" is run. But the files newly created 
in new directories will be redistributed properly, it is just for the 
older directories it won't happen.  (Directories i mean "top level" 
directories).
