Yes. 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 replica 2 volumes) . Once you have the new data brick , you can revert the process and increase the replica count . gluster volume add-brick VOLUME replica 3 arbiter 1 host1:/path/to/data/brick host3:/path/to/arbiter/brick Best Regards,Strahil Nikolov On Sat, Jul 23, 2022 at 12:07, Gilboa Davara<gilboad@gmail.com> wrote: _______________________________________________ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-leave@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/6LOFWLT7HX3KNJ...
