<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal">I was noticing some behaviour on SLES 12 Sp2 HAE <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<ol style="margin-top:0in" start="1" type="1">
<li class="MsoNormal" style="margin-left:0in;mso-list:l0 level1 lfo3">Cluster Name<o:p></o:p></li></ol>
<p class="MsoNormal" style="margin-left:1.0in">If you go to yast2 > cluster and you change the cluster name, the change is not reflected in /etc/corosync/corosync.conf that shows the default name “hacluster”<o:p></o:p></p>
<ol style="margin-top:0in" start="2" type="1">
<li class="MsoNormal" style="margin-left:0in;mso-list:l0 level1 lfo3">Expected votes<o:p></o:p></li></ol>
<p class="MsoNormal" style="margin-left:1.0in">With a 2 node cluster you have the corosync.conf configured like this for the quorum section:<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:1.0in"><o:p> </o:p></p>
<p class="MsoNormal" style="margin-left:1.0in"> provider: corosync_votequorum<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:1.0in"> expected_votes: 2<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:1.0in"> two_node: 1<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:1.0in"><o:p> </o:p></p>
<p class="MsoNormal" style="margin-left:1.0in">and it’s correct<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:1.0in"><o:p> </o:p></p>
<p class="MsoNormal" style="margin-left:1.0in">If for some reason you redo an “ha-cluster-init”on the same first node WITHOUT overwriting the corosync.conf and then you perform an “ha-cluster-join” on the second node the corosync.conf changes like this<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:1.0in"><o:p> </o:p></p>
<p class="MsoNormal" style="margin-left:1.0in"> provider: corosync_votequorum<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:1.0in"> <span style="background:yellow;mso-highlight:yellow">
expected_votes: 3<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-left:1.0in"><span style="background:yellow;mso-highlight:yellow"> two_node: 0</span><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> so it seems that cluster do not check the number of nodes but simply add a +1 every join you perform IF you DON’T overwrite the original corosync.conf.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Are 1 & 2 expected behaviour? Any experience on that?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
