Does this also happen when you issue a osd specific "tell", i.e. ceph tell osd.13 injectargs '--osd-max-backfills 4' Does this also happen when you loop over it one by one? > Did anyone see this before and/or do you have a hint on how to debug > ceph tell as it is not a daemon on its own? IIRC I have seen this, but not in combination with PGs peering / activating. Has the config change become effective on alls OSDs: verify with ceph daemon osd.13 config get osd_max_backfills (for all OSDs) Gr.
