arbiter node as you are getting the advantage of saving
on space by having this config. <br>

Since you have a new you can add this as fourth node and
create another gluster volume (replica 3) out of this
node plus the other two nodes and run vm images there as
well.</div>

<div class="gmail_extra">And thanks for the answer. The actual

To add a fully replicated node you need to reduce the replica count
to 2 and add new brick to the volume so that it becomes replica 3.
Reducing replica count by removing a brick from replica / arbiter
cannot be done from UI currently and this has to be done using
gluster CLI. <br>
AFAIR, there was an issue where vm's were going to paused state
when reducing the replica count and increasing it to 3. Not sure if
this still holds good with the latest release. <br>
<br>
Any specific reason why you want to move to full replication instead
of using an arbiter node ?<br>

To move arbiter role to a new node you can move the node to
maintenance , add new node and replace old brick with new brick.
You can follow the steps below to do that.<br>
<br>
<ul>
<li>Move the node to be replaced into Maintenance mode</li>
<li>Prepare the replacement node</li>
<li>Prepare bricks on that node.</li>
<li>Create replacement brick directories</li>
<li>Ensure the new directories are owned by the vdsm user and the
kvm group.</li>
<li># mkdir /rhgs/bricks/engine</li>
<li># chmod vdsm:kvm /rhgs/bricks/engine</li>
<li># mkdir /rhgs/bricks/data</li>
<li># chmod vdsm:kvm /rhgs/bricks/data</li>
<li>Run the following command from one of the healthy cluster
members:</li>
<li># gluster peer probe <new_node></li>
<li> add the new host to the cluster.</li>
<li>Add new host address to gluster network</li>
<li>Click Network Interfaces sub-tab.</li>
<li>Click Set up Host Networks.</li>
<li>Drag and drop the glusternw network onto the IP address of the
new host.</li>
<li>Click OK</li>
<li>Replace the old brick with the brick on the new host</li>
<li>Click the Bricks sub-tab.</li>
<li>Verify that brick heal completes successfully.</li>
<li>In the Hosts tab, right-click on the old host and click
Remove.</li>
<li>Clean old host metadata</li>
<li># hosted-engine --clean-metadata --host-id=<old_host_id>
--force-clean</li>
</ul>

When you move your node to maintenance all the vms running on that
node will be migrated to another node and since you have two nodes
up and running there should not be any problem.<br>
