All services stopped. It's likely you're a victim of a kernel backport that removed a dentry invalidation mechanism for FUSE mounts. The result is that ceph-fuse can't trim dentries. We have a patch to turn off that particular mechanism by default: https://github.com/ceph/ceph/pull/17925 I suggest setting that config manually to false on all of your clients and ensure each client can remount itself to trim dentries (i.e. it's being run as root or with sufficient capabiltities) which is a fallback mechanism. -- Patrick Donnelly _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
