Generated output file /tmp/alpha-mod.txt

# cat /tmp/alpha-mod.txt
#


The outfile gets generated but it is empty (no files get listed).


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

glusterfs-6.0-9.el7rhgs.x86_64


How reproducible:
-----------------

2/2


Steps to Reproduce:
-------------------

1. Create a volume, FUSE mount it and create a glusterfind session for it
2. Create some files from the mount point using 'touch'
3. Perform glusterfind pre followed by glusterfind post
4. Modify the contents of the file
  # echo "test" > testfile
5. Perform glusterfind pre


Actual results:
---------------

Glusterfind pre fails with the error mentioned in the description. The outfile gets generated but it does not contain any of the files that were modified.


Expected results:
-----------------

Glusterfind pre should pass and the modified files must be listed in the outfile with the tag MODIFY.
