Right. This is the reason why you get an EBUSY on Linux-2.6 & drbd-0.7 
when you try to mount a device in secondary state.

drbd-0.8 works already surprisingly good. Primary/primary is already
in SVN.... I just had not found the time to really test it 
with one of the physical parallel file systems.

But there is still item 16 on the ROADMAP, and I want to have
that in before doing the first pre release. It might happen
by the end of April
