I'd start by asking a simple question: Is there any solid reason to do an 8-way cross building gluster cluster? Beyond the unbelievable waste of space (8 way mirror) that can only be solved by creating a complex setup of alternating normal and arbiter gluster bricks, you are also literally opening yourself to countless gluster stability and performance problems due to semi-reliable cross-building network link(s). In-short, unless you really, really, really need an 8 way mirror, simply don't do it. If I were you, I'd go with the much simpler and better solution of creating two separate clusters, one in every building, making sure each VM has an active version in one cluster and a recent backup in the other (and vice versa). - Gilboa _______________________________________________ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@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/PUYQI5WTJ5CJULQFYSVOBNOYW5FUUAWH/
