<p>Hello,</p>
<p>I have a live gluster setup like this:</p>

<p>This was set up as a replica 2 and I would like now to turn into
a replica 3. I believe it's possible without loss of data
(combination of "replace-brick" and other commands), but cannot
find any docs describing the process.</p>
<p>Am I right that it is possible ? Where can I find documentation ?</p>
<p>Thanks,<br>
