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-blockl... 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?

Hi,
can anyone share some experience with these two configs?
ceph config get mds mds_session_blocklist_on_timeout true ceph config get mds mds_session_blocklist_on_evict true
If there's some network maintenance going on and the client connection is interrupted, could it help to disable evicting and blocklisting MDS clients? And what risks should we be aware of if we tried that? We're not entirely sure yet if this could be a reasonable approach, but we're trying to figure out how to make network maintenance less painful for clients. I'm also looking at some other possible configs, but let's start with these two first.
Any comments would be appreciated!
Thanks! Eugen _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-leave@ceph.io
