After upgrading to Ceph Jewel release, users should set the ‘sortbitwise’ flag to enable the new internal object sort order.
“sortbitwise” is a change in the internal sorting algorithm.
It is exposed to end-user only because of legacy (pre- jewel) compatibility.
Latest Ceph installation it should always be ‘on’
$ ceph osd set sortbitwise // To set the sortbitwise
$ ceph osd unset sortbitwise // to unset the sortbitwise
