No, there is no problem with the IP connectivity, the problem is with the DRBD. If I look 
at tcpdump log, I see that the nodes talk to each other via the configured port 7789 but 
the connection state WFConnection stays unchanged.

My main problem is certainly not this little bug with ignoring 'yes', but that the 
connection state is not changed from WFConnection to Connected and hence the secondary 
node is not used.
