[Linux-cluster] RHCS / DRBD / MYSQL

[Arjuna Christensen]

FYI, the relevant changes to my cluster.conf were:

	   <resources>
            <ip address="192.168.111.1" monitor_link="1"/>
            <script file="/etc/init.d/drbdcontrol" name="drbdcontrol"/>
            <script file="/etc/init.d/asterisk" name="asterisk"/>
            <script file="/etc/init.d/mysql" name="mysql"/>
            <fs device="/dev/drbd0" force_fsck="0" force_unmount="0" fsid="11607" fstype="ext3" mountpoint="/var/lib/mysql" name="mysqlfs" options="" self_fence="1"/>
         </resources>
         <service autostart="1" domain="asterisk" name="asteriskcluster">
            <ip ref="192.168.111.1">
               <script ref="drbdcontrol">
                  <fs ref="mysqlfs">
                     <script ref="mysql">
                        <script ref="asterisk">
                        </script>
                     </script>
                  </fs>
               </script>
            </ip>
         </service>

Apparently it didn't like the <script ref="mysql"/> or <script ref="asterisk"/>. I'm aware now that I'm running an incredibly old (read: last year) version, but this has fortunately allowed me to work around it.

Thanks to Fabio & Lon in the IRC channel! :)

He is using an ubuntu package made up by a CVS snapshot from 20070315. All 
the versions of the binaries are coming from the same snapshot.
