            Bug ID: 1215668
           Summary: [geo-rep + tiering]: georep fails to create session on
                    tiered volume
           Product: GlusterFS
           Version: mainline
         Component: geo-replication
          Severity: urgent
          Assignee: bugs at gluster.org
          Reporter: rhinduja at redhat.com
                CC: bugs at gluster.org, gluster-bugs at redhat.com



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

When you try to create a geo-rep session having master volume as type: Tier, it
fails with error "Index initialization failed".

log snippet:
============

ation 'Volume Geo-replication Create' failed on localhost : Index
initialization failed

This error comes when gluster volume set returns non-zero for
"changelog.changelog:" and "geo-replication.indexing:". On tiered volume, any
set command is failing which could be the reason for georep failing its
session.


Version-Release number of selected component (if applicable):
=============================================================
glusterfs-server-3.7dev-0.1015.gita3578de.el6.x86_64


How reproducible:
=================
always


Steps to Reproduce:
===================
1. Create Master cluster
2. Create Slave cluster
3. Create and start master volume (2x2=4)
4. Create and start slave volume (2x2=4)
5. attach-tier to master volume (2x2=5)
6. attach-tier to slave volume (2x2=5)
7. Create a geo-rep session between master and slave volume.

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

Fails to create with error "Index initialization failed"

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

It should successfully create the georep session.
