This issue is being tracked here: http://tracker.ceph.com/issues/36346
The problem was caused by a backport of the wrong commit which
unfortunately was not caught. The backport was not done to Luminous;
only Mimic 13.2.2 is affected. New deployments on 13.2.2 are also
affected but do not require immediate action. A procedure for handling
upgrades of fresh deployments from 13.2.2 to 13.2.3 will be included
in the release notes for 13.2.3.
