<p>Hi,</p>
<p>I'm afraid I still need some help.</p>
<p>When I originally set up my gluster (about 3 years ago), I set it
up as Distributed-Replicated without specifying a replica count
and I believe that defaulted to a replica 2. I have 4 servers with
3 RAIDs attached to each server. This was my result:</p>
<pre class="moz-quote-pre" wrap=""> Number of Bricks: 6 x 2 = 12
Transport-type: tcp
Bricks:
Brick1: hydra1:/gluster1/data
Brick2: hydra1:/gluster2/data
Brick3: hydra1:/gluster3/data
Brick4: hydra2:/gluster1/data
Brick5: hydra2:/gluster2/data
Brick6: hydra2:/gluster3/data
Brick7: hydra3:/gluster1/data
Brick8: hydra3:/gluster2/data
Brick9: hydra3:/gluster3/data
Brick10: hydra4:/gluster1/data
Brick11: hydra4:/gluster2/data
Brick12: hydra4:/gluster3/data
</pre>
<p>If I understand this correctly I have 6 sub-volumes with Brick2
replica of Brick1, Brick4 of Brick3, etc. Correct ?</p>
<p>I realize now that it would probably have been better to specify
a different order, but now I cannot change it.</p>
<p>Now I want to store oVirt images on the Gluster and it requires
either replica 1 or replica 3. I need to be able to reuse the
bricks I have and was planning to remove some bricks, initialize
them and add them back as a replica 3. <br>
</p>
<p>Am I supposed to remove 6 bricks, one from each sub-volume ? Will
that work ? Will I lose storage space ? Can I just remove a brick
from each server and use those for the replica 3 ? <br>
</p>
<p>Thanks for all the help.<br>
</p>
