to benchmark multiple mds is disable the dynamic load balancer (make
MDBalancer::try_rebalance()
return at the very beginning), and use 'ceph mds tell \* export_dir

Please first delete the old mds log, then run mds with "debug_mds = 15".

The crash didn't happen immediately after 'ceph: mds0 caps stale', I
have no idea what went wrong. Could you setup 'netconsole' to get

could you enable mds debugging for a few seconds (ceph daemon mds.x

debug_mds 0). and upload /var/log/ceph/mds.x.log to somewhere.

This seems like reconnect timeout. you can try enlarging mds_reconnect_timeout
config option.
Which version of kernel are you using?
Yan
R_KEEPALIVE2. So the kernel client couldn't reliably
detect the event that network cable got unplugged. It kept waiting for
new events from the disconnected connection.
