RE: [Linux-cluster] Two nodes don't see each other



JF,

I used this one for the new panadol and it works fine : 

<?xml version="1.0"?>
<cluster config_version="6" name="LNX-CLU">
        <fence_daemon clean_start="1" post_fail_delay="0" post_join_delay="3"/>

                <clusternode name="panadola" votes="1">

                                <method name="1">
                                        <device name="panadola-ilo"/>
                                </method>
                        </fence>
                </clusternode>
                <clusternode name="panadolb" votes="1">

                                <method name="1">
                                        <device name="panadolb-ilo"/>
                                </method>
                        </fence>
                </clusternode>
        </clusternodes>
        <cman expected_votes="1" two_node="1"/>
        <fencedevices>
                <fencedevice agent="fence_ilo" hostname="panadola-mp" login="jimi" name="panadola-ilo" passwd="jimi_only"/>
                <fencedevice agent="fence_ilo" hostname="panadolb-mp" login="jimi" name="panadolb-ilo" passwd="jimi_only"/>
        </fencedevices>
        <rm>
                <failoverdomains/>
                <resources>
                </resources>
          
        </rm>
</cluster>

My cluter-start scripts and modules :

service ccsd start
