            Bug ID: 1350179
           Summary: entry failed error with symlink files and dirs using
                    distributed geo replication
           Product: GlusterFS
           Version: 3.7.11
         Component: geo-replication
          Severity: medium
          Assignee: bugs at gluster.org
          Reporter: hostingnuggets at gmail.com

Description of problem:
Distributed geo-replication generates errors in its geo-replication geo.log
file on tge master when replicating symlinked directories or files. An example 
of such an error taken from this log file:

[2016-06-25 23:57:58.566375] E [master(/data/myvolume/brick):784:log_failures]
_GMaster: ENTRY FAILED: ({'gfid': 'f2156f11-505a-4bb7-a697-8da4a97e622d',
'entry': '.gfid/aa5198e7-fc88-4135-863b-a69e451df450/vphn.c', 'stat': {'atime':
1466618772.882145, 'gid': 0, 'mtime': 1462143151.0, 'mode': 41471, 'uid': 0},
'link': '../../../../../arch/powerpc/mm/vphn.c', 'op': 'SYMLINK'}, 2)

This error is also reported in the "gluster volume geo-replication status
detail" command under the FAILURES column. The number reported under the
FAILURES count matches the number of error lines found in the log file
mentioned above.

Nevertheless the symlinked files and directories exists on the slave so they
have been replicated but still an error is reported.

Version-Release number of selected component (if applicable):
GlusterFS 3.7.11 on Debian 8

How reproducible:
I just took a linux kernel tarball which contains a few symbolic links of files
and directories and unpacked it onto my volume and then started geo-replication
for the first time.

Steps to Reproduce:
1. setup two nodes replica volume
2. unpack linux-4.6-rc6.tar.xz (taken from kernel.org) onto that volume
(contains 23 symbolic links)
3. setup distributed geo-replication to slave node and start geo-replication

Actual results:
23 FAILURES reported under the status details of geo replication command and 23
errors in the geo.log file on the master

Expected results:
0 FAILURES and 0 error lines in the geo.log log file

Additional info:
Using Debian 8.5 on all nodes
