No downtime and data migration by hands needed.Just want to let you guys know that Kevin had bad experience doing add-bricks when VMs are online. We are still not able to recreate this bug. So I would advise you to do an offline migration for now.I found no informations about creating a replicated volume with asingle node, is it possible ?Yes, with "force" option, if you really need that.Also is it possible to add a third arbitrary node to an existing 2replica volume ?Yes, starting from v3.8.Regards,Oleksandr_______________________________________________Gluster-users mailing list
