It's also only a measure of how much of the tuneable memory usage it should aim for, but OSDs also have a separate need for ram that is not negotiable (often at startup and recovery) and for that usage, preferences are not applied, it will try to use the ram it needs in order to fix itself regardless of the admins preferences. -- May the most significant bit of your life be positive. _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-le...@ceph.io
