If you want to go active/active.  I'd recommend Samba + CTDB + Gluster. 

You want true clustering, and a system that can handle the locking etc.

I'd layer normal DFS to do "namespace" control, and to help with
handling failover, or just use round robin DNS.

Thanks,

Hello,

what do you mean by "true" clustering ?
We can do a Windows Failover cluster (1 virtual ip, 1 virtual name), but
this mean using a shared storage like SAN.

Then it depends on your network topology. If you have multiple geographical
sites / datacenter, then DFS-R behave a lot better than Gluster in
replicated mode. Users won't notice any latency,
At the price that replication is async.
