Following commands will also show nodes not connected:

On SUSE Cloud6, use : drbdadm cstate
On SUSE Cloud7, use : drbdadm status


Disconnect secondary and cleanup :
1. drbdadm disconnect postgresql
2. drbdadm secondary postgresql
3. drbdadm connect --discard-my-data postgresql

On the other node (the split brain survivor), connect to start sync :
drbdadm connect postgresql
