          Hardware: x86_64
                OS: Linux

+++ This bug was initially created as a clone of Bug #1688231 +++

Description of problem:
This issue is seen with the RHHI-V usecase. VM images are stored in the gluster
volumes and geo-replicated to the secondary site, for DR use case.

When IPv6 is used, the additional mount option is required
--xlator-option=transport.address-family=inet6". But when geo-rep check for
slave space with gverify.sh, these mount options are not considered and it
fails to mount either master or slave volume

Version-Release number of selected component (if applicable):
RHGS 3.4.4 ( glusterfs-3.12.2-47 )

How reproducible:

Steps to Reproduce:
1. Create geo-rep session from the master to slave

Actual results:
Creation of geo-rep session fails at gverify.sh

Expected results:
Creation of geo-rep session should be successful
