OK, I clearly misunderstood something.
All I am trying to achieve is have the same process handle the client
and server aspects, so that mounting the AFR-ed FS gets the local server
going, too. Is that not achievable? Because what I have _seems_ to
actually work, only I cannot mount the FS from a single server from a
remote node, I just get "end point not connected". But files between the
two servers do get replicated.
Attached is a sample config of what I'm talking about. The other server
is the same only with home1 and home2 volumes reversed.

Hi Gordan,
Schedulers are only available for Unify translator. AFR doesnt support
NUFA.
Usually for HPC type workload, we do two separate mounts.
1) Unify (with NUFA scheduler) of all the nodes
2) Unify (with RR scheduler) of all AFRs. Each AFR mirrors two nodes.

Hi,
I'm trying to use the NUFA scheduler and it works fine between the
machines that are both clients and servers, but I'm not having much
luck with getting client-only machines to mount the share.
I'm guessing that the problem is that I am trying to wrap a "type
cluster/afr" brick with "option scheduler nufa" with a
protocol/server, and export that. Is there any reason why this
shouldn't work? Or do I have to set up a separate AFR brick without
"option scheduler nufa" to export with a brick of "type protocol/server"?
