What do you think about requiring that the sortbitwise OSDMap flag be set before ceph-osd will start? I think this would let us drop all the Sortbitwise comparator stuff immediately. Jewel already issues a health warning if all OSDs are jewel and the flag isn't set. We can make a note in the upgrade notes. ? 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
