I don't know what conclusions he reached, or even if he has already reached any conclusions at all. I, for one, would be really interested in knowing how well (or how poorly) Atoms deal with Ceph. Maybe Wido can share some thoughts on this one? :-) -Joao -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
