ah I see. I unpacked the DMC-xxx.jar und made my changes to "src/drbd/help-progs/drbd-gui-helper". After re-zipping it and starting it, the GUI was no longer useable. 
As I looked deeper into the jar file I saw system calls like  "/usr/local/bin/drbd-gui-helper all".

So I changed the file on my cluster server (srv-ovz01 and srv-ovz02) -> and now I can select the drbd device.

-> worked for me.

Best wishes,

	Matthias
