this seems to indicate that the two nodes aren't communication with each 
other. the cs:StandAlone means that the other side isn't connected and 
the Unknown for st and ds means the node cant get the state of the other 
server with drbd. do you have firewalls blocking traffic? something else 
interrupting the communication between the nodes?
