So I did. But, nothing changed. For this scenario there shouldn't be
fencing involved at all, right? I just issued 
crm ressource migrate nfs ha1, which led to the same failure as the last
days.

However, in the logs now I got:
[  100.995696] block drbd4: Split-Brain detected, 0 primaries, automatically solved. Sync from this node

Any ideas?

Cheers,
Georg
