[Gluster-users] geo replication issue

[Krishna Verma]

Hi Sunny,

Thanks for your response. Yes " usr/libexec/glusterfs/python/syncdaemon/gsyncd.py'" was missing at slave. 

I have installed " glusterfs-geo-replication.x86_64" rpm and then the session is Active now. 

But now I am struggling with the indexing issue. Files more than 5GB in master volume is not getting sync with slave. I have to delete the geo replication session and erase the indexing like below then after creating the new session large files start sync with slave. 

How we can avoid this Gluster behavior in geo replication? Also can we monitor the real time data sync between master and slave by any GUI method? 

I was also searching for the implementation docs of "geo replication over the internet for distributed volume", but can't find any. Do you have one? 

Appreciate for any help. 

 

#gluster volume geo-replication gv1 sj-gluster01::gv1 delete
Deleting geo-replication session between gv1 & sj-gluster01::gv1 has been successful
]# gluster volume set gv1 geo-replication.indexing off

/Krishna
