scalability options

hello list!

i'm looking for a distributed filesystem scalable up to a few terabytes
that will run on freebsd 5.x. i've long been a fan of coda and would like
to use it for this application, but i've read of an inherited volume limit
of 4GB, and successful installations up to 20GB.

this application could really take advantage of the client caching for a
seperate ~4GB volume, and the rest of the data only needs to be replicated
among multiple servers; it won't need to be cached on the clients.

is it at all possible to have this size volume? i can dedicate as much RVM
space as needed, and with server to server replication, i don't
necessarily need to do backups of the large volume, but i would likely do
them for the small volume.

i'm looking at openafs currently, but it doesn't seem production-ready for
freebsd. i've also read of porting progress for GFS and sgi's xFS, but
they don't seem to have the same set of features.

is there anyone using any kinda of self-replicating distributed filesystem
with support of multi-terabyte volumes?
