<p>Dear Stefan,</p>
<p><br>
</p>
<p>what about your expectation on upgrading the OS to CentOS 8
Stream? <br>
</p>
<p>Are there any advantages?</p>
<p><br>
</p>
<p>Regards,</p>
<p>Felix<br>

Hi Strahli,
<div class=""><br class="">
</div>
<div class="">Thank you for the quick answer! Sorry I have to ask
again: as far as I can see, Gluster keeps all information about
peers, bricks, in /var/lib/glusterd. So if I migrate to a new
OS, it seems that I have to restore them. Or would you suggest
rather to re-generate them by repeating all "peer probe ..."
and "volume brick-add ..." commands?</div>
