How do I can set full/nearfull ratios correctly? $ceph injectargs '--mon_osd_full_ratio 96' parsed options $ ceph injectargs '--mon_osd_near_full_ratio 94' parsed options ceph pg dump | grep 'full' full_ratio 0.95 nearfull_ratio 0.85 Setting parameters in the ceph.conf and then restarting mons does not affect ratios either. -- 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
