Hello Pedro, This is a known bug in standby-replay MDS. Please see the links below and patiently wait for the resolution. Restarting the standby-replay MDS will clear the warning with zero client impact, and realistically, that's the only thing (besides disabling the standby-replay MDS completely) that you can do. https://tracker.ceph.com/issues/40213 https://github.com/ceph/ceph/pull/48483 On Tue, Sep 19, 2023 at 6:51 AM Pedro Lopes <pavila@sensei.tech> wrote:
So I'm getting this warning (although there are no noticeable problems in the cluster):
$ ceph health detail HEALTH_WARN 1 MDSs report oversized cache [WRN] MDS_CACHE_OVERSIZED: 1 MDSs report oversized cache mds.storefs-b(mds.0): MDS cache is too large (7GB/4GB); 0 inodes in use by clients, 0 stray files

What is telling me? Is it just that case of the cache size needing to be bigger? Is it a problem with the clients holding onto some kind of reference (documentation says this can be a cause, but now how to check for it).
