I was under the impression that "ceph-disk activate" would take care of setting OSD weights. In fact, the documentation for adding OSDs, the "short form", only talks about running ceph-disk prepare and activate: http://ceph.com/docs/master/install/manual-deployment/#adding-osds This is also how the Ceph cookbook provisions OSDs ( https://github.com/ceph/ceph-cookbook) and we've been using it successfully in other scenarios, without having to manually set weights.
