Description Dhairya Parmar 2023-08-01 09:35:37 UTC

+++ This bug was initially created as a clone of Bug #2228039 +++

Description of problem: If OSD(s) is/are laggy (due to certain conditions like network cut-off, etc) then it might make clients laggy(session might get idle or cannot flush dirty data for cap revokes). Therefore have a config option that can be used to defer evicting/removing "laggy" client sessions until OSDs are no longer laggy. Log a warning to the cluster indicating the situation.
