May I add that's it's already a strange state as AFAIK when no management task is executed BOTH .drbdctrl should be in secondary state. It only becomes primary when drbdmanage change 'something' (move disk, reconfigure, etc ...). > b) forget everything in a), remove drbdmanage, and install LINSTOR. You'll save you some time.
