Ceph » mgr » Dashboard

An error occurrs when marking an OSD down while the `noup` OSD flag is enabled and eventually removing the OSD. Some errors occur in the frontend and the OSD list is not shown anymore due to the created constellation. `ceph osd dump` isn't returning four OSDs anymore but three.

        osds = self.get_osd_map()

is technically the result of `ceph osd dump` and is used as base for collecting data about OSDs, hence one OSD can't be found to add data to it as the previous command didn't return all OSDs.
