Description Raghavendra Talur 2016-04-26 20:34:45 UTC

+++ This bug was initially created as a clone of Bug #1330052 +++

Description of problem:
It is possible that some xlators don't print debug/trace logs even when required.
In such cases debugging an existing setup without recompiling becomes very difficult. If libglusterfs/gluster wind/unwind had a debug log builtin then such dependency on every xlator would be reduced.


Version-Release number of selected component (if applicable):
mainline and all previous versions


How reproducible:
Always

    libglusterfs: Add debug and trace logs for stack trace
    
            Backport of http://review.gluster.org/13448
            commit c4d67a8338b42d6485f49999f310cbb9ed5359c5
    
    It has become very difficult to identify the xlator which returned
    negative op_ret. Being able to just change the log level and
    visualize the stack is helpful in such cases.
