clvmd init script fails to start or stop with exclusively activated volumes in the cluster in RHEL 5.6

Issue

• On system bootup, the clvmd service fails on activating the volumes when using HA-LVM with clvmd, and a volume is activated exclusively on another node

• The clvmd init script fails when starting if a volume is activated exclusively on another node

  Starting clvmd: 
  Activating VG(s):   Error locking on node node2: Volume is busy on another node
    0 logical volume(s) in volume group "myvg" now active
                                                             [FAILED]
  

• When clvmd fails to start on bootup because a volume is busy on another node, the clvmd service will not stop on shutdown, causing the cman service stop to fail, and the system will not shutdown

• Access a node's storage page in the Conga web interface results in the error "Host responded - clvmd failed to start"
