<p>Thanks Strahil,</p>
<p>I have a couple of questions. <br>
</p>
<p>My /gluster1 is mounted, but no "data" folder, I suppose that
will be created when I reset the brick. I see two versions of the
reset-brick operations:</p>
<blockquote>
<pre>gluster reset-brick <VOLNAME> <SOURCE-BRICK> start
gluster reset-brick <VOLNAME> <SOURCE-BRICK> <NEW-BRICK> commit
</pre>
</blockquote>
<p>I assume I should use the first version. When I specify the
<SOURCE-BRICK> do I just put the number or do I have to
include the "Brick" prefix ?</p>
<p>As for the brick layout, you hit the nail on the head. My VMs'
went down and it was very painful to get everything back up to
speed. I thought I had implemented the correct layout, I guess I
was wrong. Which one do you suggest ?</p>
<p>Thanks so much,<br>
</p>

Yep, you have to bring back hydra4:/gluster1/data

<p>Strahil,</p>
<p>did some more digging into the heal info output.</p>
<p>Found also the following:</p>
<blockquote>
<pre>[...]
Brick hydra4:/gluster1/data
Status: Transport endpoint is not connected
Number of entries: -
Brick hydra3:/arbiter/2
<gfid:2aa223b0-77f5-441e-bc76-34c8d459eeaa>
[...]

</blockquote>
<p>So, to augment what I wrote before, the errors
appear in "Brick hydra3:/gluster3/data" and "Brick
hydra3:/arbiter/2", plus that "Transport endpoint is
not connected" for "Brick hydra4:/gluster1/data".</p>
<p>I need to add that hydra4:/gluster1 is the RAID
that had major hardware failure.</p>
