Is there any other info you can think of that might be useful? I want to make sure I capture all the evidence needed if it happens again. If you can dump the MDS cache that might turn out to be useful too; otherwise there's probably not much you can get unless your kernel includes dynamic debug and you can play with the /sys/kernel/debug/ceph that is described at http://docs.ceph.com/docs/master/cephfs/troubleshooting/#kernel-mount-debugging But I'll leave that up to Zheng or somebody who works on the kernel client. -Greg _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
