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. Thanks kasturi On Fri, Sep 15, 2017 at 12:41 PM, Abi Askushi <rightkicktech@gmail.com> wrote:
Hi all,
I see in the ovirt guides that a gluster volume replica 3 with 1 arbiter is recommended. Why not simple replica 3? Is it due to the higher replication data that would cause performance issues?
What I am observing is that a VM running on the server which has the arbiter brick has slower read performance then when the same VM runs on another server with a normal brick. Has anyone observed this? Is it because the arbiter does not have the real data on it?
Thanx, Alex
