DRBD stores it's meta data at the end of the used device. So it cannot find it 
anymore since you moved the end away from the meta data. That's the reason why 
one should follow the DRBD user's guide which tells you to do the resize while 
drbd is online, so drbd still knows where it's meta data is and can move it to 
the new end of the device. Offline resize is much more difficult.
