[Gluster-users] Failsafe replication between two DC - getting trash in files.

[Craig Carl]

Alex - 
If you want to move the replication to the server-side the best way to do that is by changing your access method to NFS. Gluster 3.1 (beta) includes a NFS server (gNFS) implemented as a translator. It is very fast, for files < 64KB it can be faster than the native GlusterFS client. If you layer RRDNS and UCARP over your mirrored nodes you can achieve the same level of redundancy and HA as with the native client. If you move to NFS we suggest a "storage network" between the Gluster storage servers to offload that traffic from the public interfaces. The 3.1 beta is -

Hi Alex - Доброе утро (по крайней мере здесь) 

The problem with replication on both the server and the client is that the server does not (I believe) have an awareness of what the client is doing. I did post a thread asking about best practices for replication (I was leaning towards server side to keep that traffic local), and was told that client side replication was recommended and supported. 

I think you're seeing corruption on your copies because both the client and the server are replicating. 

Also - the reason you didn't get an email directly from me last time was that I only send to the list unless requested otherwise. I'm copying you directly this time. 

Thanks, 

James Burnash, Unix Engineering

Mailing list seems to be very slow. I still did not get answer from James Burnash. So wh not have replication on client and server side? It's seems to be logical, I've just extended this sample http://www.gluster.com/community/documentation/index.php/Setting_up_AFR_on_two_servers_with_server_side_replication
