Hi Eugene, Disabling blocklisting on eviction is a pretty standard config. In my experience it allows clients resume their session cleanly without needing a remount. There's docs about this here: https://docs.ceph.com/en/latest/cephfs/eviction/#advanced-configuring-blocklisting I don't have a good feeling if this will be useful for your network intervention though... What are you trying to achieve? How long will clients be unreachable?
