[ovirt-users] GlusterFS Hyperconvergence

[Tiemen Ruiten]

Thanks Doron,

I would initially start with a 3 host cluster, possibly adding more hosts
later on. Is this enough to ensure integrity of the Gluster storage domain,
eg. in case of host failure?

What are recommendations (if they exist) for the type of Gluster volume for
a 3-5 host cluster (replicated or replicated distributed, number of
replica's)?

Would this setup already leverage libgfapi instead of FUSE?
