This could be related with a rename and locking issue still pending to 
be merged [1]. If that's the real cause, 3.6.2 won't solve the problem 
yet, though it can alleviate some other issues.

You can increase log verbosity using this command:

     gluster volume set <volname> client-log-level TRACE

This will add *a lot* of log messages from all internal calls.

To upgrade from 3.6.1 to 3.6.2 (assuming you installed 3.6.1 from rpm), 
you can take the new rpm's [2] and they should do the upgrade 
automatically. To make things easier, this should be done with all 
gluster volumes unmounted and stopped.
