Eventually, however, that somehow magically resolved itself, so I did went ahead with adding the resource constraints.<o:p></o:p></span></p>

I think you need a colocation constraint to prevent it from trying to start the LVM resource on the DRBD secondary node. I used to run LVM-over-DRBD clusters but don't any more (switched to NFS backend storage), so I don't remember the exact syntax, but you
certainly don't want the LVM resource to start on node2 at this point because it will certainly fail.<o:p></o:p></p>

<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">It may not be running on node1 because it failed on node2, so if you can get the proper colocation constraint in place, things may work after you do a resource cleanup. (I stand ready to be corrected by someone more knowledgeable who can
spot a configuration problem that I missed).<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">If you still get failure and the constraint is correct, then I would try running the lvcreate command manually on the DRBD primary node to make sure that works.<o:p></o:p></p>
