The arbiter is useless with only 1 data brick,as it contains only medatata and if you have 1 full brick (data + metadata) and 1 arbiter (only metadata) in the volume, you could end in a metadata split brain (risk is the same like&nbsp; replica 2 volumes) .<div><br></div><div>Once you have the new data brick , you can revert the process and increase the replica count .</div><div><br></div><div>gluster volume add-brick VOLUME replica 3 arbiter 1 host1:/path/to/data/brick host3:/path/to/arbiter/brick</div><div><br></div><div>Best Regards,</div><div>Strahil Nikolov&nbsp;</div><div> <br> <blockquote style="margin: 0 0 20px 0;"> <div style="font-family:Roboto, sans-serif; color:#6D00F6;"> <div>On Sat, Jul 23, 2022 at 12:07, Gilboa Davara</div><div>&lt;gilboad@gmail.com&gt; wrote:</div> </div> <div style="padding: 10px 0 0 20px; margin: 10px 0 0 0; border-left: 1px solid #6D00F6;"> _______________________________________________<br clear="none">Users mailing list -- <a shape="rect" ymailto="mailto:users@ovirt.org" href="mailto:users@ovirt.org">users@ovirt.org</a><br clear="none">To unsubscribe send an email to <a shape="rect" ymailto="mailto:users-leave@ovirt.org" href="mailto:users-leave@ovirt.org">users-leave@ovirt.org</a><br clear="none">Privacy Statement: <a shape="rect" href="https://www.ovirt.org/privacy-policy.html" target="_blank">https://www.ovirt.org/privacy-policy.html</a><br clear="none">oVirt Code of Conduct: <a shape="rect" href="https://www.ovirt.org/community/about/community-guidelines/" target="_blank">https://www.ovirt.org/community/about/community-guidelines/</a><br clear="none">List Archives: <a shape="rect" href="https://lists.ovirt.org/archives/list/users@ovirt.org/message/6LOFWLT7HX3KNJ7FTOPBN6LWVTEXHMBH/" target="_blank">https://lists.ovirt.org/archives/list/users@ovirt.org/message/6LOFWLT7HX3KNJ7FTOPBN6LWVTEXHMBH/</a><br clear="none"> </div> </blockquote></div>
