I doubt this solution is You're right. However, pros : over 2 years this solution has proven to work *perfectly* for us, Reboots are rare and done using pools (~10 servers each time), NFS was horrible to handle and we lost data everytime traffic was intense. Cons : this was over linux. I believe NFS over FreeBSD works better (by I still have my linux servers... and they work great so..). > reliable and flexible enough.
