Hi All Kernel client: 4.6.4-1.el7.elrepo.x86_64 MDS version: 10.2.2 OS: CentOS 7
I have Cephfs mounted on a few servers, I see the following in the log approx every 20 secs on all of them: kernel: ceph: mds0 caps went stale, renewing kernel: ceph: mds0 caps stale kernel: ceph: mds0 caps renewed I'm trying to debug a few intermittent nfs related issues (which may or may not be cephfs related) and I'm just wondering if these lines are anything to worry about. I've mounted on a server that is almost completely idle and I'm still seeing those lines every 20 secs. Ceph health is OK and the MDS server seems pretty happy although I am occasionally seeing some "closing stale session" lines in the ceph-mds log but I think that's a separate issue. Thanks, David
