[ovirt-users] oVirt deployment with GlusterFS with replica 3 arbiter 1

Hello community, I am planing to deploy a lab with oVirt and I would like to know if the design in my mind has any flaws. Current plan is to deploy oVirt on 2 workstations with 24GB of RAM and 8 threads each while the 3rd machine will be a VM in a public Cloud and will be used for GlusterFS arbiter. Is it a problem if the arbiter is a vanilla CentOS 7 . I am affraid that oVirt will require all GlusterFS nodes to be also oVirt Hosts, but the VM will lack the necessary resources and I would like to not use that 3rd system. Is this idea possible ? Thanks for reading this confusing post and I hope I managed to explain my idea. Best Regards, Strahil
