-====================================
- Kernel client troubleshooting (FS)
-====================================
-
-If there is an issue with the cephfs kernel client, the most important thing is
-figuring out whether the problem is with the client or the MDS. Generally,
-this is easy to work out. If the kernel client broke directly, there
-will be output in dmesg. Collect it and any appropriate kernel state. If
-the problem is with the MDS, there will be hung requests that the client
-is waiting on. Look in ``/sys/kernel/debug/ceph/*/`` and cat the ``mdsc`` file to
-get a listing of requests in progress. If one of them remains there, the
-MDS has probably "forgotten" it.
-We can get hints about what's going on by dumping the MDS cache:
-ceph mds tell 0 dumpcache /tmp/dump.txt
-
-And if high logging levels are set on the MDS, that will almost certainly
-hold the information we need to diagnose and solve the issue.
