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:
-----------------
Always
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
