Well obviously all which are in the kernel.

Depends on you usage. OK, I guess you did not want to hear this.

ext3 is the conservative good choice, even beyond 2 TB AFAIK (I think up
to 32 TB are supported).

We had some issues with reiser3, very good speed, but when it crashes to
hard, we had no chance to get anything back from it.

Right now we are running about 300 TB on xfs and so far are pretty happy
with it (though are quite a few people at CERN). Good performance and
good stability on recent Linux kernels. Just make sure that you have
write barriers enabled (default since 2.6.18(?)).
