Well, technically they are. My worry is that it's more likely that racks will have significantly vary capacity (i.e. crush weight) due to, say, 1 full rack and a second 1/2 rack. If the policy forces replicas be placed across racks things won't balance well. I suppose there should be an argument like --min-racks that controls that threshold? sage -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
