Hi Stefan, probably. Its 2 compute nodes and there are jobs running. Our epilogue script will drop the caches, at which point I indeed expect the warning to disappear. We have no time limit on these nodes though, so this can be a while. I was hoping there was an alternative to that, say, a user-level command that I could execute on the client without possibly affecting other users jobs. Thanks and best regards, ================= Frank Schilder AIT Risø Campus Bygning 109, rum S14 ________________________________________ From: Stefan Kooman <stefan@xxxxxx> Sent: Tuesday, October 17, 2023 11:13 AM To: Frank Schilder; ceph-users@xxxxxxx Subject: Re: stuck MDS warning: Client HOST failing to respond to cache pressure On 17-10-2023 09:22, Frank Schilder wrote: > Hi all, > > I'm affected by a stuck MDS warning for 2 clients: "failing to respond to cache pressure". This is a false alarm as no MDS is under any cache pressure. The warning is stuck already for a couple of days. I found some old threads about cases where the MDS does not update flags/triggers for this warning in certain situations. Dating back to luminous and I'm probably hitting one of these. > > In these threads I could find a lot except for instructions for how to clear this out in a nice way. Is there something I can do on the clients to clear this warning? I don't want to evict/reboot just because of that. echo 2 > /proc/sys/vm/drop_caches on the clients .... does that help? Gr.
