<p dir="ltr">I think that everything should be in cluster.</p>
<p dir="ltr">DLM & cLVMd are prerequisites for your cluster resources -> which means that the cluster stack needs to be able to control them.</p>
<p dir="ltr">Also, if you remove the cloned DLM & cLVMd resources - the cluster will not know that a node has a failed dlm.</p>

</span></font><div>Hi,<br />
<br />
i'm a big fan of simple solutions (KISS).<br />
Currently i have DLM, cLVM, GFS2 and OCFS2 managed by pacemaker.<br />
They all are fundamental prerequisites for my resources (Virtual Domains).<br />
To configure them i used clones and groups.<br />
Why not having them managed by systemd to make the cluster setup more overseeable ?<br />
<br />
Is there a strong reason that pacemaker cares about them ?<br />
<br />
