+++ This bug was initially created as a clone of Bug #1498391 +++

Description of problem:
When disabling changelog for a volume which is participating in the geo-replication, there should be a clear warning that this could affect the geo-replication session in which that particular volume is participating. 
Changelog currently disables with no warning. 

[root@dhcp42-35 ~]# gluster volume set master changelog.changelog off
volume set: success
[root@dhcp42-35 ~]#

The patch actually disallows this to happen. So there is a discrepency between what the patch does and what the bugzilla problem description says. I realized this after merging the patch. Is my understanding correct that we should disallow it? If so then the text has to be corrected here.

Comment 4 Kotresh HR 2017-11-21 06:21:16 UTC
If geo-rep session is established, we should not allow the changelog to disable. 
Disable and enabling it during the same session could cause geo-rep not to sync data.
