Version-Release number of selected component (if applicable):glusterfs-3.4.0.57rhs-1


How reproducible: Didn't try to reproduce. 


Steps to Reproduce:
I observed this crash while doing the following steps.

1. create and start a geo-rep relationship between master and slave. 
2. create data on master using the command, "./crefi.py -n 100 --multi -b 10 -d 10 --random --max=2K --min=1K /mnt/master/"
3. then run this "for i in {1..10}; do ./crefi.py -n 100 --multi -b 10 -d 10 --random --max=2K --min=1K --fop=hardlink /mnt/master/ ; done"

Actual results: Geo-rep crashed because of failing to create brick status file


Expected results: First of all, geo-rep shouldn't fail to create some status file, even if it fails it shouldn't crash.
