ah ok... i will try this.

another question for my testing:
- i start GLFS with 4 nodes (dist - repl+repl)
- on node5 and 6 i change the volume file
- then i start node5 and 6 (now the layout is dist - repl+repl+repl)
  i guess that's not recommended :)
  although it seem to work somehow.

btw. the manual says with GLFS 1.3.x and higher server and client binary are the same file.
does that mean i can write everything in one volumen file and start only one glusterfs binary?
