Andreas-

I applied both changes you mentioned and the behavior still exists.  
Here is my current configuration:

    node nodea \
         attributes standby="off"
    node nodeb \
         attributes standby="off"
    primitive ClusterIP ocf:heartbeat:IPaddr2 \
         params ip="192.168.1.3" cidr_netmask="32" \
         op monitor interval="30s"
    primitive datafs ocf:heartbeat:Filesystem \
         params device="/dev/drbd0" directory="/data" fstype="ext3" \
         meta target-role="Started"
    primitive drbd0 ocf:linbit:drbd \
         params drbd_resource="drbd0" \
         op monitor interval="31s" role="Slave" \
         op monitor interval="30s" role="Master"
    primitive drbd1 ocf:linbit:drbd \
         params drbd_resource="drbd1" \
         op monitor interval="31s" role="Slave" \
         op monitor interval="30s" role="Master"
    primitive fence-nodea stonith:fence_ipmilan \
         params pcmk_host_list="nodeb" ipaddr="xxx.xxx.xxx.xxx"
    login="xxxxxxx" passwd="xxxxxxxx" lanplus="1" timeout="4" auth="md5" \
         op monitor interval="60s"
    primitive fence-nodeb stonith:fence_ipmilan \

         op monitor interval="1min"
    primitive patchfs ocf:heartbeat:Filesystem \
         params device="/dev/drbd1" directory="/patch" fstype="ext3" \
         meta target-role="Started"
    group web datafs patchfs ClusterIP httpd
    ms drbd0clone drbd0 \
         meta master-max="1" master-node-max="1" clone-max="2"
    clone-node-max="1" notify="true" target-role="Master"
    ms drbd1clone drbd1 \

    clone-node-max="1" notify="true" target-role="Master"
    location fence-on-nodea fence-nodea \
         rule $id="fence-on-nodea-rule" -inf: #uname ne nodea
    location fence-on-nodeb fence-nodeb \

If the cluster is fully down, I start corosync and pacemaker on one 
node, the cluster fences the other node but the services do not come up 
until the cluster-recheck-interval occurs.  I have attached the 
corosync.log from this latest test.
