I had the exact same problem (on Redhat though...) MQ and Message Broker that needed clustering... First we tried NFS V4 (clustered using IBM System Automation for multi-platform) and got really bad response time... Then we used IBM System Automation to cluster both MQ and MB and dropped the NFS solution... Works great with great response time...
