[Gluster-users] server side afr, workstation unify?

I am having trouble with the following setup, hope that somebody will be able 
to help. 

We have a couple of workstations and two file-servers. Let's just keep it at 2 
workstations for now, because I can just add more clients later I guess. So 
the workstations are called echo and reality, and the servers are dream and 

I am wondering whether it is possible to have a unified filesystem between 
echo and reality, using the nufa scheduler to keep things local as much as 
possible, and at the same time to have afr running on the servers neo and 
dream so that those guys each have a complete copy of the workstations (echo 
and reality). 

I can get it to work with only afr, or only unify, but combining the two 
somehow does not do it. The best I got so far was to have empty directories 
on the servers.

Worst case is that I go with not doing the unified thing, but it would be nice 
because it is so much faster and most of the time, files are just accessed 
locally anyway. With only client side afr, nfs seemed to be faster (with 
varying performance translators), and with server side afr, nfs and glusterfs 
where about the same speed - with the big advantage of not having a single 
point of failure. :)

Maybe this setup just doesn't make any sense at all ...

Well, hope somebody has some suggestions!
