<div dir="ltr"><div>Hello,</div><div><br></div><div>Due to a change in the switch in one of the datacenters now I have an odd behaviour in the cluster.</div><div><br></div><div>I am using cman with corosync and pacemaker. The versions are:</div><div><br></div><div>pacemaker-1.1.10-14.el6_5.3.x86_64</div><div>corosync-1.4.1-15.el6_4.1.x86_64</div><div>cman-3.0.12.1-49.el6.x86_64</div><div><br></div><div>The problem is, when I launch /etc/init.d/pacemaker start and the cman_tool launch corosync, I don't see any UDP traffic, so the cluster is "broken"</div><div><br></div><div>But if I launch manually the same command "corosync -f" I do see udp traffic and the totem is correctly sent between nodes.</div><div><br></div><div>It all began with the change in the switch, but I set the tcpdump in the hosts and I do not see traffic.</div><div><br></div><div>I have tried the multicast and unicast configuration, different network, but all with the same behaviour.</div><div><br></div><div>What am I missing?</div><div><br></div><div>Best Regards</div><div><br></div>-- <br><div class="gmail_signature"><div dir="ltr"><div><b>Roberto Muñoz Gómez</b><br></div><div dir="ltr"><br></div></div></div>
