Hello,<br>
<blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">
<br>
Due to a change in the switch in one of the datacenters now I have an odd<br>
behaviour in the cluster.<br>
<br>
I am using cman with corosync and pacemaker. The versions are:<br>
<br>
pacemaker-1.1.10-14.el6_5.3.x86_64<br>
corosync-1.4.1-15.el6_4.1.x86_64<br>
cman-3.0.12.1-49.el6.x86_64<br>
<br>
The problem is, when I launch /etc/init.d/pacemaker start and the<br>
cman_tool<br>
launch corosync, I don't see any UDP traffic, so the cluster is "broken"<br>
<br>
But if I launch manually the same command "corosync -f" I do see udp<br>
traffic and the totem is correctly sent between nodes.<br>
<br>
It all began with the change in the switch, but I set the tcpdump in the<br>
hosts and I do not see traffic.<br>
<br>
I have tried the multicast and unicast configuration, different network,<br>
but all with the same behaviour.<br>
<br>
What am I missing?<br>
<br>

<br>
I'm pretty sure main problem is that:<br>
- corosync -f uses /etc/corosync/corosync.conf as a config file<br>
- cman_tool join uses /etc/cluster/cluster.conf as a config file <br></blockquote></blockquote></span></blockquote><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"><span class=""><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">
Make sure to "replicate" (specially udpu/udp, ...) configuration from<br>
corosync.conf to cluster.conf and I'm pretty sure it will work.<br></blockquote></blockquote></span></blockquote><div><br></div><div><br></div><div>It worked!</div><div><br></div><div>I didn't knew cman_tool do not use corosync.conf.
