Try to change the service element as follows:
                  <service autostart="0" domain="failover" name="RHTTPD">
                          <ip ref="10.43.100.204"/>
                          <script ref="httpd"/>
                  </service>
What tells you rgmanager now?

Also try to get used to the rg_test tool. That helps.

Try e.g. rg_test /etc/cluster/cluster.conf
..
