Hi Kotresh, Just to update for sync issue.
I erased the indexing by doing gluster volume set <vol-name> indexing off, after stopping the geo-rep session and then start the session. Now its syncing. For your query: Yes, this include the time take to write 1GB file to master. geo-rep was not stopped while the data was copying to master. …. It's better if gluster volume has more distribute count like 3*3 or 4*3 :- Are you refereeing to create a distributed volume with 3 master node and 3 slave node? /Krishna From: Krishna Verma Sent: Thursday, August 30, 2018 3:52 PM To: 'Kotresh Hiremath Ravishankar' <khire...@redhat.com> Cc: Sunny Kumar <sunku...@redhat.com>; Gluster Users <gluster-users@gluster.org> Subject: RE: [Gluster-users] Upgrade to 4.1.2 geo-replication does not work Hi Kotresh, Yes, this include the time take to write 1GB file to master. geo-rep was not stopped while the data was copying to master. But now I am trouble, My putty session was timed out while copying data to master and geo replication was active. After I restart putty session My Master data is not syncing with slave. Its Last_synced time is 1hrs behind the current time. I restart the geo rep and also delete and again create the session but its “LAST_SYNCED” time is same. Please help in this. ….

Can I setup both the master as “Active” ? Nope, since it's replica, it's redundant to sync same files from two nodes. Both replicas can't be Active. Also, when I copy a 1GB size of file from gluster client to master gluster volume which is replicated with the slave volume, it tooks 35 minutes and 49 seconds. Is there any way to reduce its time taken to rsync data. How did you measure this time? Does this include the time take for you to write 1GB file to master? There are two aspects to consider while measuring this. 1. Time to write 1GB to master 2. Time for geo-rep to transfer 1GB to slave. In your case, since the setup is 1*2 and only one geo-rep worker is Active, Step2 above equals to time for step1 + network transfer time. You can measure time in two scenarios 1. If geo-rep is started while the data is still being written to master. It's one way. 2. Or stop geo-rep until the 1GB file is written to master and then start geo-rep to get actual geo-rep time. To improve replicating speed, 1. You can play around with rsync options depending on the kind of I/O and configure the same for geo-rep as it also uses rsync internally. 2. It's better if gluster volume has more distribute count like 3*3 or 4*3 It will help in two ways. 1. The files gets distributed on master to multiple bricks 2. So above will help geo-rep as files on multiple bricks are synced in parallel (multiple Actives) NOTE: Gluster master server and one client is in Noida, India Location. Gluster Slave server and one client is in USA. Our approach is to transfer data from Noida gluster client will reach to the USA gluster client in a minimum time. Please suggest the best approach to achieve it.
