<p>Hi list,</p>
<p>I have a number of stacked resources replicating from 2 hosts to
a common third host. There are three resources 'stuck' waiting
for a connection with a state "Inconsistent". I have tried
discarding the data on this third node and reconnecting with <b>drbdadm
connect --discard-my-data</b> but I'm not having any luck.</p>
<p>I even (lv)removed the backing device, (lv)created a new volume,
said yes to remove the existing drbd meta-data:</p>

<p>This third node, connected using protocol A, is intended for
disaster recovery only so none of these resources should ever have
been the primary so I am leaning away from a split-brain however
the symptoms appear to me to be like a split brain. I'm not
seeing anything related to split-brain in the logs. <br>
</p>
<p>The resources are UpToDate on the primaries:</p>

I am keen to get these three resources replicating. Any
suggestions what I'm missing?<br>
