<p>I see nowhere to set this node's IP yet the docs say this
resource file "must be distributed across all nodes in the
cluster — in this case, three<br>
nodes." What is the point of the convirt-U res file on
trk-kvm-02?<br>

<p>Oh my!!!!</p>
<p>2 weeks of missing that typo and frustration. Thank you both
Yannis and Peter. Peter, I thought you were pointing out the
answer to my question - which file is it failing to find. I
normally copy the .res file to ensure they are always identical,
and it was correct on nodes 1 and 2....</p>
<p>I really appreciate the help guys, it all makes sense now. I
was worried that I had a serious misunderstanding in what I was
doing.</p>

After fixing that you should be able to create the metadata
and initialize the stacked device by:</div>
<div><br>
</div>
<div>On trk-kvm-01 (assuming that this is the primary node):</div>
<div>drbdadm create-md --stacked convirt-U<br>
</div>
<div><br>
</div>
<div>On trk-kvm-03:</div>
<div>drbdadm create-md convirt-U #this will create the
required metadata on the underlying device
(i.e /dev/trk-kvm-03-vg/convirt). No need to transfer
metadata manually from trk-kvm-01)<br>
</div>
<div><br>
</div>
<div>On trk-kvm-01:</div>
<div>drbdadm --stacked adjust convirt-U</div>
<div><br>
</div>
<div>On trk-kvm-03:</div>
<div>drbdadm adjust convirt-U</div>
<div><br>
</div>
<div>On trk-kvm-01:</div>
<div>drbdadm --stacked -- --overwrite-data-of-peer primary
convirt-U<br>
</div>
<div>cat /proc/drbd </div>
