Although I am a fan of plan 9 in general, I don't really see how posting a link to the Wikipedia article is useful.

I have a question about it: can anyone tell how it deals with redundancy?

It seems to be distributed. If you are running Plan 9 on 3 machines, and one goes down, what happens to the rest of the system. Does it become unavailable?

A lot of people don't know anything about Plan 9.

Sure, but is Hacker _News_ really the place to learn?

[thirsteh]

Sure. It's been stated many times that Hacker News is for anything that might be interesting to hackers, not just "news" (anything that happened relatively recently.)
