Hello, with jewel we always used the python crush optimizer which gave us a pretty good distribution fo the used space. Since luminous we're using the included ceph mgr balancer but the distribution is far from perfect and much worse than the old method. Is there any way to tune the mgr balancer? Currently after a balance we still have: 75% to 92% disk usage which is pretty unfair Greets, Stefan _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
