It looks like you have a network problem.
1. What is the resource configuration?
2. What is your network configuration?
Now that you've got a split-brain, you will need to repair that before
you can try to connect them again. Is this ver. 8.3.x?
http://www.drbd.org/users-guide/s-resolve-split-brain.html
Once cleared up, on each node try;
modprobe drbd
drbdadm attach <res>
drdbadm connect <res>
Then 'cat /proc/drbd' and see what it says. If it's still showing
'StandAlone', then it detected a split-brain again. If both show
'WFConnection', then your network issue has not been resolved.
