This sort of thing was done to death IIRC in the 80s. It was dropped for a while because, at the scale of file server usage in the 90s, nfs file servers were fine. At least from what I read today, google does it now in GFS. There is an open source version of something that claims to do provide it based on Hadoop (http://hadoop.apache.org/core/) although the hadoop setups I have seen use NFS for distributing files (!). I vaguely remember gluster talking about failover and recovery (http://www.gluster.org/). Have you done a literature search? I don't get the feeling that you have. Thanks ron
