Did I miss something or is your NFS volume exactly that: a single point of failure. I think you ruled out the DRb solution too quickly. Shared resources on NFS volumes are always prone to failure. Plus it doesn't scale well because too many processes accessing the index directory will inevitably lead to poor performance or a complete deadlock. I've come to the conclusion that the "Share Nothing" approach works best and SOAs are the way to go. I prefer talking to a single index server and not worry about the details. I don't care whether it is a single server or a load balanced cluster that services my request. -- Andy _______________________________________________ Ferret-talk mailing list [email protected] http://rubyforge.org/mailman/listinfo/ferret-talk
