Here is the relevant snippet of my configuration that shows the location<br>
and colocation set up. As well as what I *think* I am asking it to do.<br>

<br>
** Ensuring that the resources from one failover node do not start up on<br>
the other nodes giving -500 points.<br>

You can't have bidirectional colocation, i.e.. either specify "colocation colocMDSOSS1 -500: anchorOSS1 MDSgroup" or "colocation colocOSS1MDS -500: MDSgroup anchorOSS1", but not both. The dependency loop error means pacemaker is tossing one of these away. For some more detail check the Resource Constraints chapter of Pacemaker explained (<a href="http://www.clusterlabs.org/doc/en-US/Pacemaker/1.1/html/Pacemaker_Explained/" target="_blank">http://www.clusterlabs.org/<u></u>doc/en-US/Pacemaker/1.1/html/<u></u>Pacemaker_Explained/</a>) or the mailing list archives (this has come up a few times in recent memory).<br>

I knew something was amiss with my configuration. I originally wasn't sure if colocation was bidirectional or not.<br clear="all"><br>Bobbie Lind<br>Systems Engineer<br><i><b>Solutions Made Simple, Inc (SMSi)</b></i><br>
