Description Ravishankar N 2015-11-27 12:13:57 UTC
+++ This bug was initially created as a clone of Bug #1286017 +++

Description of problem:

The arbiter brick anyway stores zero-byte files. There's no point of sending writes to the arbiter brick, only for it to unwind the writes without performing any action.

    afr: skip healing data blocks for arbiter
    
    Backport of  http://review.gluster.org/12777
    
    1 ....but still do other parts of data-self-heal like restoring the time
    and undo pending xattrs.
    
    2. Perform undo_pending inside inodelks.
    
    3. If arbiter is the only sink, do these other parts of data-self-heal
    inside a single lock-unlock sequence.
