<div>Hi Andrew,</div>
<div>yes, this clarifies a lot.</div>
<div>Seems that it is really time to throw away the plugin.</div>
<div>The CMAN solution wont be able (at least from the documentation) to attach new nodes without reconfiguration and restart CMAN on the existing nodes.</div>
<div>The alternative is corosync 2.x.</div>
<div>ClusterLabs has a quite long list of corosync versions from branch 2.0, 2.1, 2.2 und 2.3.</div>
<div>Beside the current reported issue of version 2.3, which version does ClusterLabs use for its regression test.</div>
<div>I found somewhere a note for 2.1.x, is this true ?</div>

I worked it out...<br/>
<br/>
The Red Hat changelog for 1.1.8-2 originally contained<br/>
<br/>
+- Cman is the only supported membership & quorum provider, do not ship the corosync plugin<br/>
<br/>
When this decision was reversed (when I realised no-one was seeing the ERROR logs indicating it was going away), I neglected to re-instate the following distro specific patch (which avoided conflicts between the ID used by CMAN and Pacemaker):<br/>
<br/>
diff --git a/configure.ac b/configure.ac<br/>

<br/>
So Pacemaker < 6.4 is talking on slot 10, while Pacemaker == 6.4 is using slot 9.<br/>
This is why the two versions cannot see each other :-(<br/>
I'm very sorry.<br/>
