[Erik Osterman]

GlusterFS has a ways to go in stability, but is certainly on the right track. GlusterFS is a FUSE based filesystem that is mostly POSIX compliant. It is trivial to setup and configure, scales into the petabytes*, decentralized, and can easily grow and shrink capacity by adding storage bricks. The development community is active and extremely helpful.
