I interpreted the results as the same RBD image was being concurrently used by two fio jobs -- which we strongly recommend against since it will result in the exclusive-lock ping-ponging back and forth between the two clients / jobs. Each fio RBD job should utilize its own backing image to avoid such a scenario. -- Jason _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
