With OpenAIS clusters, you can only have quorum if more than half the nodes in the cluster are online, so in a two node cluster, if one node goes down, you always lose quorum. If no-quorum-policy is set to "stop", resources on the surviving node will be stopped. If you want the surviving node to attempt to STONITH the other node and take over its resources, you need to set no-quorum-policy to "ignore".
