Failing to respond to cache pressure?

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

 



Hello all,

I'm seeing some warnings regarding trimming and cache pressure. We're running 0.94.1 on our cluster, with erasure coding + cache tiering backing our CephFS.

     health HEALTH_WARN
            mds0: Behind on trimming (250/30)
            mds0: Client 74135 failing to respond to cache pressure

The trimming error popped up after restarting the mds, but then went away on its own. However, "failing to respond to cache pressure" persists.

The cluster is basically idle at the moment (no reads/writes when watching ceph -w), so this is very confusing to me.

Is there any way to identify the hostname or IP address of client 74135, so I can check the client itself?

Thanks much,
Lincoln
