I am using OCFS2 (which is like GFS) for the filesystem to handle multiple servers reading and writting from a disk that is mounted on more than one server, is that still a bad idea?
Also I read if I use GFS. How can this be true unless I attach the GFS volume to an ethernet card?

You can't. And probably you don't even want it because you should never
mount the same file-system on more than one server (at least if you are
not using something like GFS).

P.S. I hope you will *not* put critical data on such array...
