--- Comment #4 from Nithya Balachandran <nbalacha at redhat.com> ---
This issue is also tracked in https://github.com/gluster/glusterfs/issues/239


For directory structure dir-1/dir-2/dir-3
Earlier behaviour:

gf_defrag_fix_layout (mydir):
  lookup mydir
  process mydir (migrate files)
  for every directory d in mydir
     setxattr (fix-layout, d)  <-- calculates new layout and saves it to disk.
At this point, any child dirs of 'd' which hash to the newly added bricks will
not be listed by a dht_readdirp on 'd'
     gf_defrag_fix_layout (d)  
     set_commit_hash (d)
  done  
done



New behaviour:

gf_defrag_fix_layout (mydir):
  lookup mydir

  for every directory d in mydir
     gf_defrag_fix_layout (d)  
  done

  setxattr (fix-layout, mydir) 
  process mydir (migrate files)
  set_commit_hash (mydir)

done


With this change, all child dirs will be healed before the parent directory's
layout is changed so this issue will not exist.
