I was playing with CODA a few weeks ago in a test environment. I could get it to mostly work the way I wanted, but it appears that there are some limitations that I don't like. For one, having to "login" to CODA using clog (or maybe I misunderstood the docs on this point?) I want to be able to list a clustered filesystem in fstab and be usable like any other UFS or NFS filesystem - no logging in, permissions and ownership work, etc. Better yet, an approach like Google's File System. If I run out of space or speed, let me throw more boxes at it. Without losing the filesystem. The machine comes onto the network, notifies one of the chunk servers that it's available and how much disk it's got. The chunk servers can now send chunks of data to it. Data is automatically replicated to multiple disk servers, and requests are shared across those servers that have copies of the same data. Chunk servers share metadata so they aren't a single point of failure.
