Ok, let's report a better error message when applying this service id. Moving to 5.2

Comment 8 Redouane Kachach Elhichou 2022-02-07 14:00:44 UTC

The behavior (from the point of view of MDS) is correct. Numeric service_ids are not allowed on the MDS service (https://github.com/ceph/ceph-container/issues/97) however so far this was not documented properly. I checked with MDS team and they will be opening a PR to update the doc to reflect this restriction. A check at orchestrator level would be added to report a better error message for this scenario as well.
