[Linux-cluster] cman : exceeds two node limit ?

[FM]

The more I play with CS the more I am frustrated  ;-)

Why do I received that :
kernel: CMAN: Join request from SERVER rejected, exceeds two node limit

my cluster.conf is very simple :

<?xml version="1.0"?>
<cluster config_version="6" name="webfarm">
        <fence_daemon post_fail_delay="0" post_join_delay="3"/>
        <clusternodes>
                <clusternode name="cagliari" votes="1">
                        <fence/>
                </clusternode>
                <clusternode name="como" votes="1">
                        <fence/>
                </clusternode>
                <clusternode name="lecce" votes="1">
                        <fence/>
                </clusternode>
        </clusternodes>
        <cman/>
        <fencedevices/>

                                <failoverdomainnode name="como"

                        </failoverdomain>
                </failoverdomains>
                <resources/>
        </rm>
</cluster>
