Why do my HA-LVM volumes fail to stop cleanly when rgmanager starts on Red Hat Enterprise Linux 4?

                <resources>
                        <ip address="192.168.1.10" monitor_link="1"/>
                        <fs device="/dev/volgroup02/logvol02" force_fsck="0" force_unmount="1" fsid="42119" fstype="ext3" mountpoint="/home/filesystem1" name="filesystem1" options="" self_fence="0"/>
                        <fs device="/dev/volgroup03/logvol03" force_fsck="0" force_unmount="1" fsid="1585" fstype="ext3" mountpoint="/home/filesystem2" name="filesystem2" options="" self_fence="0"/>
                        <lvm lv_name="logvol02" name="volgroup02" vg_name="volgroup02"/>
                        <lvm lv_name="logvol03" name="volgroup03" vg_name="volgroup03"/>
                        <script file="/etc/cluster/ccb_cis" name="appserver"/>
                </resources>
                <service autostart="1" domain="domain1" name="service1">
                        <ip ref="192.168.1.10"/>
                        <fs ref="filesystem1"/>
                        <fs ref="filesystem2"/>
                        <lvm ref="volgroup02"/>
                        <lvm ref="volgroup03"/>
