Description of problem:
=======================
Geo-replication is faulty on RHGS 3.5


The logs throw the following warning: 
[2019-04-11 03:03:06.736471] W [gsyncd(config-get):305:main] <top>: Session config file not exists, using the default config    path=/var/lib/glusterd/geo-replication/master_10.70.42.250_slave/gsyncd.conf

Is this a new prerequisite for setting up geo-rep in RHGS 3.5 ?


Also, the following OSErrors can be seen in the master:

How reproducible:
================
Always

Steps to Reproduce:
==================
The same steps to set up geo-replication as mentioned in RHGS documentation

Actual results:
===============
Geo-rep status is FAULTY

Expected results:
=================
Geo-rep status should be ACTIVE/PASSIVE


Additional info:
===============
Will be attaching sosreports
