The memory target (and <1G is too small by far) is only directing the things that *can* be tuned, there are other things the OSD needs memory for which are not optional and those will take memory even if you set the limits to X GB. Also, while you may find some lower limit that works in some fashion, later events such as rebalancing,recovery,backfills and upstart-checks *will* need more memory even if only temporarily. What you are setting is more or less like setting the autopilot engine level on an airplane at the cruising altitude, it does *not* control how much engine is needed for take-off, landings or emergencies. -- May the most significant bit of your life be positive. _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
