[DRBD-user] drbd9.0.1 on debian 8

[Rudolf Kasper]

Hi,

i'm trying to install the latest drbd9.0.1.1 on debian 8.
Everything seems to run fine, but then when i added a new resource i got 
this error message in syslog:
Feb 13 00:05:41 ha-storage-1 drbdadm[18206]: [

when i try to start the drbd-service:
/etc/init.d/drbd start
[....] Starting drbd (via systemctl): drbd.serviceJob for drbd.service 
failed. See 'systemctl status drbd.service' and 'journalctl -xn' for 
details.
  failed!


the status page displays the following:

running drbdsetup /dev/drbd0 primary --overwrite-data-of-peer results in
API mismatch!
         API version drbdsetup: 1 kernel: 2
         header size drbdsetup: 8 kernel: 8



Would be nice if anyone can help me soon, the servers has to go into 
production end of this week (today i've to define the downtime we have 
to schedule tomorrow)


Thanks a lot
Kind regards
