Clustering with Freebsd

[yf-263]

Please read the Google.com's GoogleFS.

And now we are working on implementing a GoogleFS like Cluster Storage
for my Employer, which is target for the web, mail, IM, Netdisk, etc.
services, and we have more than 1,000 million users.

For GoogleFS, the upper layer is like an asymmetric cluster filesystem
as www.lustre.org; and in block layer, like V9FS' Venti. What is also
our target ;)

Deeper info is welcomed to be discussed :)
