I agree with what Steve Whitehouse has said thus far, but I want to add: The latest/greatest upstream fsck.gfs2 has the ability to recreate pretty much any and all damaged system structures and system files, but there's only so much it can do. That's why I suggested trying the experimental RHEL6 version, which isn't too far out of date from the upstream version. It's much better at recovering single blocks that have been overwritten, rather than a group of blocks. It's actually quite sophisticated in recreating things.
