            Bug ID: 1600405
           Summary: [geo-rep]: Geo-replication not syncing renamed symlink
           Product: GlusterFS
           Version: mainline
         Component: geo-replication
          Assignee: bugs at gluster.org
          Reporter: khiremat at redhat.com
                CC: bugs at gluster.org



Description of problem:
Geo-rep sometimes fails to sync the rename of symlink
    if the I/O is as follows

      1. touch file1
      2. ln -s "./file1" sym_400
      3. mv sym_400 renamed_sym_400
      4. mkdir sym_400

The file 'renamed_sym_400' failed to sync to slave



Version-Release number of selected component (if applicable):
mainline

How reproducible:
Few times, looks like race

Steps to Reproduce:
1. setup geo-rep, start it.
2. Stop geo-rep 
3. On master do following I/O
        1. touch file1
        2. ln -s "./file1" sym_400
        3. mv sym_400 renamed_sym_400
        4. mkdir sym_400
4. Find the brick on which rename_sym_400 is present on master
   and kill that brick
5. Start geo-rep so that other bricks processes there changelog first
6. Once other bricks are in changelog crawl, bring back brick which was down.
7. It also moves to changelog but 'renamed_sym_400' doesn't sync


Actual results:
'renamed_sym_400' doesn't sync

Expected results:
'renamed_sym_400' should sync
