[1] CODA, OpenAFS, GFS, OpenGFS, Lustre (Am I missing any?).

Speaking of it, does any of you know if any of these file systems are reliable against failure of a single (or a few nodes) out of say 150?

How about automatic rebuild and such things?

Hmm, well, it could probably work well if you don't have a lot of data (then you don't need to create a lot of partition/volumes). I found their (OpenAFS/Coda) limited sizes a major problem. They're not exactly the speediest things I've layed my hands upon either... Intermezzo seems more promising - but is still to unmature for production settings.

I'd like to gather any information possible since we're in the process of building a cluster with ~ 150 nodes and about 100-140 GB/node of 'free' hard drive space.
To large - to large :-\
