I am running this with 3+ TiB of storage. I know that isn't close to what you
are running, but it is above the 2 TiB mark that can cause problems. Mine
seems to be running pretty stable. The storage is ultimately on a Coraid
device. It's like a SAN over ethernet. It even supports be connected and
driven by more than one computer at once, and it's block level storage.
If you have a cluster running kernel 2.6.16, you could try OCFS2. When Debian
Etch upgrades to kernel 2.6.16, I will probably start messing with it.
