Thanks! However, I still don't really understand why I am seeing this.
The first time I had this, one of the clients was a remote user dialling in via VPN, which could indeed be laggy. But I am also seeing it from neighbouring hosts that are on the same physical network with reliable ping times way below 1ms. How is that considered laggy?

Hi Janek,There was some documentation added about it here: https://docs.ceph.com/en/pacific/cephfs/health-messages/There is a description of what it means, and it's tied to an mds configurable.On Mon, Sep 18, 2023 at 10:51 AM Janek Bevendorff <janek.bevendo...@uni-weimar.de> wrote:Hey all, Since the upgrade to Ceph 16.2.14, I keep seeing the following warning: 10 client(s) laggy due to laggy OSDs ceph health detail shows it as: [WRN] MDS_CLIENTS_LAGGY: 10 client(s) laggy due to laggy OSDs mds.***(mds.3): Client *** is laggy; not evicted because some OSD(s) is/are laggy more of this... When I restart the client(s) or the affected MDS daemons, the message goes away and then comes back after a while. ceph osd perf does not list any laggy OSDs (a few with 10-60ms ping, but overwhelmingly < 1ms), so I'm on a total loss what this even means. I have never seen this message before nor was I able to find anything about it. Do you have any idea what this message actually means and how I can get rid of it?
