Re: [ovirt-users] Recommended gluster setup

Hi , yes, you are right. Since arbiter brick has only metadata and data for the vm has to be served from one of the other two replicas, read is slow. Arbiter is a special subset of replica 3 volumes and is aimed at preventing split-brains and providing same consistency as a normal replica 3 volume with out consuming 3x space. You could use replica 3 and no issues with that.
