No unfortunately just a typo. I tried to create a partition first on both
sides before creating a drbd pair to see if that made any difference. It did
not.

Tried to create a filesystem on the disks without drbd to see if the mkfs
command was broken or something. That worked fine. 

Have no ideas anymore so any ideas on what to do / try are welcome.
