Description of problem:
=======================

In a scenario, where files are synced to slave and replace brick is issued on master. This can cause hybrid crawl if the replaced brick becomes ACTIVE, it crashes with permission denied and becomes passive.

Version-Release number of selected component (if applicable):
=============================================================
glusterfs-3.7.9-8

How reproducible:
=================
Yet to try second time.


Steps to Reproduce:
===================
1. Create Master and Slave volume. Create geo-rep session between them
2. Create data on Master and let it sync to slave.
3. Stop the existing session.
4. Initiate Replace brick commit for one of the brick
5. Start geo-rep immediately

Actual results:
===============

Replace brick starts (Hybrid) crawl and crashes.


Expected results:
=================

Worker should not crash
