If i copy some kvm images to the ceph cluster, the cache osds always run full. Is that normal? Is there a miss configuration? thanks best regards Patrik _______________________________________________ ceph-users mailing list [email protected] <mailto:[email protected]> http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com <http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com>
