Recovery. See:
http://www.drbd.org/docs/working/
chapter "manual split brain recovery"
I have seen this often during the cluster setup but it shold not happen during
operation afterwards, when nobody is playing around with the cluster.
Also be sure you read
http://www.drbd.org/docs/install/
section "Automatic split brain recovery policies"
Did you install everything accordingly?
