Re: Understand Geo Replication of a big Gluster

[Kotresh Hiremath Ravishankar <khiremat@xxxxxxxxxx>]

Hi Axel,

You don't need single server with 140 TB capacity for replication. The slave (backup) is also a gluster volume similar to master volume.

So create  the slave (backup) gluster volume with 4 or more nodes to meet the capacity of master and setup geo-rep between these two volumes.

Geo-replication is between two gluster volumes and not between gluster volume and single node.

Thanks,

Hello 

Im new on GlusterFS - so a warm hello to everyone here...

Im testing GlusterFS since some Weeks in different configurations for a big Media Storage

Currently for start we plan a distributed / Replicated Gluster with for Nodes (4x70Tb)

I tryed this within a Test Area on differenzt Virtual Machines - works fine.

But for security Reason we also plan Geo Replication of the Whole Gluster. I have read Doc  - but one thing i dont understand:

For example our Start Gluster has 4 Nodes (4x70TB  Replicated and Distributed) i have 140TB Capacity.

So when i want to Geo Replicate this Volume i dont have a sigle Server wich is able to store 140GB (or later more) - but i can have several Backup Servers with a total Sice of 140TB

So my Question 

How can i say Gluster FS in Geo Replication to use all of this Backup Servers to GEO REplicate the whole Storage using all Backup Server.

Best Regards
