Hi again, I just read (and reread, and again) the chapter of Ceph Cookbook on upgrades and http://docs.ceph.com/docs/jewel/rados/operations/crush-map/#tunables and figured there's a way back if needed. The sortbitwise flag is set (repeering was almost instant) and tunables to "hammer". There's a lot of data shuffling going on now, so fingers crossed.
