For sufficiently recent clients we do this for you (clients send some
metadata like hostname, which is used in the MDS to generate an
easier-to-understand identifier).
To do it by hand, use the admin socket command "ceph daemon mds.<id>
session ls" command, and look out for the client IP addresses in the
address part of each entry. By the way, there have been various other
bugs in 3.13-ish kernels, so you should consider using either a more
recent kernel or a fuse client.

Hello Ceph Experts,
lately, "ceph status" on our cluster often states:
mds0: Client CLIENT_ID failing to respond to capability release
How can I identify which client is at fault (hostname or IP address)
from the CLIENT_ID?
What could be the source of the "failing to respond to capability
release" -
Linux kernel on the client too old? We use ceph-0.94.2 on the cluster,
and the CephFS kernel client on the clients (kernel 3.13.0 on Ubuntu
12.04
and Ubuntu 14.04). But it's possible that there's a machine with an
older Kernel around somewhere ...
Cheers and thanks,
Oliver
