           Summary: Incomplete conservative merge for split-brained
                    directories
           Product: GlusterFS
           Version: 3.7.1

+++ This bug was initially created as a clone of Bug #1180545 +++

Description of problem:
 While performing conservative merge, we bail out of the merge if we encounter
a
 file with mismatching gfid or type. What this means is all entries that come
 after the mismatching file (during the merge) never get healed, no matter how
 many index heals are done.

How reproducible:
Always

Steps to Reproduce:
(1).Create 1x2 volume, fuse mount it.
(2).Bring bricks down alternatively and creates files inside directory from
mount.
(3).At least one of the files must have same file name so that we have a gfid
mismatch when (2) is done.
(4) Trigger index heal.

Actual results:
Conservative merge does not happen fully.

Expected results:
It must.
