Viewing CephFS Client Debugging

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I'm looking for the debug messages in Client.cc, which uses ldout
(library debugging). I increased the client debug level for all
daemons (i.e. under [global] in ceph.conf) and verified that it got
set:

$ ceph --admin-daemon /var/run/ceph/ceph-mon.issdm-3.asok config show
| grep client
"client": "20\/20",

After I mount and make a couple files, I expect to see some debugging
activity, but the log is empty. Logging into the client and checking
results in:

$ ls -l /var/log/ceph/ceph-client.admin.log
-rw-r--r-- 1 root root 0 Feb 27 10:19 /var/log/ceph/ceph-client.admin.log

Is there a flag I am missing? I'm a little confused since the client
isn't really managed by a daemon like the MDSs, OSDs, and MONs are.

Things I tried: changing the permissions of /var/log/ceph, using both
the kernel and FUSE client, redirecting the logs to syslog, setting
the name of the log (i.e. log file = x in ceph.conf), checking
dmesg/kern.log.


Thanks!

Michael
