While I'm sure this is possible with OpenGFS, I don't think it is the best solution for a setup like you describe. OpenGFS doesn't scale to a large number of nodes like you seem to think it could grow. You may want to take a peek at lustre. I hope this helps. --Brian Jackson On Saturday 27 September 2003 11:35 pm, Tracy R Reed wrote: > I just read an article about iSCSI in Linux Magazine and it got me > thinking.
