i have a problem with a 2 node cluster with this conf:

                 <clusternode name="TEST1" nodeid="1" votes="1">
                 <clusternode name="TEST2" nodeid="2" votes="2">
         <cman expected_votes="2"/>

all is ok but when node 2 goes down quorum dissolved but resources is 
not stopped, here log:

clurgmgrd[1302]: <emerg> #1: Quorum Dissolved
kernel: dlm: closing connection to node 2

ccsd[964]: Cluster is not quorate.  Refusing connection.

cluster recognized that quorum is dissolved but resource manager doesn't 
stop resource, ip address is still alive, filesystem is still mount, 
i'll expect an emergency shutdown but it does not happen....
