If you're referring to https://tracker.ceph.com/issues/57675, it got into 16.2.14, although there was another issue where running a `ceph orch restart mgr` or `ceph orch redeploy mgr` would cause an endless loop of the mgr daemons restarting, which would block all operations, that might be what we were really dealing with here. That didn't have a tracker afaik, but I believe was fixed by https://github.com/ceph/ceph/pull/41002. That got into 16.2.4, but if the version being upgraded from was earlier than this, the issue would have had to have been resolved before upgrade could actually happen.
