Hi, 

I've mixed a lenny32 on a non-64Bit processor machine und a 64Bit machine: 
The lenny32 (prax2) don't want to connect:

prax2: before-resync-target handler returned 3, dropping connection.

The 64Bit node (prax1) wants to sync but:

I've installed both machines these days.

Update userland tools on both sides? - I took the latest kernel ... 

Download drbd sources an install them? -  I tried it: 

prax2:~# aptitude install drbd8-source

Any ideas?
