Hi Dan, thank you for the link. I read it as well as the linked conversation in the rook project. I don't get it why the fast shutdown should be better than the "normal" shutdown in which the OSD annouces its shutdown directly. Are there cases where the shutdown of the OSD takes longer until its markdown message is sent? Travis on the rook project mentioned the shutodwn issued IO interruptions from 20 to 30 seconds. (https://github.com/rook/rook/pull/4328#issuecomment-554480275) This is something I would expect if a complet host break down (e.g. caused by a hw failure) and only the heartbeat timeouts detect this. But not on a regular shutdown.
