MDS blocklist/evict clients during network maintenance

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
