[Gluster-users] Configuration validation needed

[Julien Cornuwel]

Hi,


I will soon have to deploy a glusterFS across several servers. Here are
my goals :

- Every server can access the all filesystem
- Every file must be replicated

I used a combination of Replicate and Distribute to be able to add new
servers. 

Each server storage is divided in two bricks (primary and secondary).
First server's primary storage is replicated on second server's
secondary. Second server's primary is replicated on third servers
secondary and so on.

And then, I use Distribute across these replicated volumes. I think this
should work, but could you please review the attached configuration file
for errors ?


Regards,
