Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.


After fixing an other error I started to see the following error on my DRBD:

kernel: block drbd0: BAD! BarrierAck #2778697761 received, expected 

Can anybody explain what the BarrierAck error means?
What is the cause of the problem?
How to solve the problem?

Thanks for any hints.
