[Linux-cluster] CMAN connectivity problem

[Manuel Bujan]

Hi people,

We are trying to set up a two nodes cluster with the latest cvs source from RedHat and when we are going to start both nodes we get that the first node form a quorum without problems, but the second one never get connected at cman level and remain trying to connect with the following error:

Dec 16 15:30:25 atmail-2 ccsd[3260]: Initial status:: Inquorate
Dec 16 15:30:28 atmail-2 kernel: CMAN: sending membership request
Dec 16 15:31:03 atmail-2 last message repeated 21 times

Our cluster.conf file is the following:

<?xml version="1.0"?>
<cluster name="ISQCLUSTER" config_version="2">
        <cman two_node="1" expected_votes="1">
                <multicast addr="224.0.0.1"/>

Any hints ????

We are using kernel 2.6.9, and we have applied all the patches availables for it
