Yes, I'm positive. There's only one metadata device on the system. I've sent you a link off-list where you can get a dump of it. If needed, I might be able to give you remote access to the system, but it's via serial console and might be a bit painful. (I doubt you'd want to use the IPMI in the server unless you should happen to be a fan of Internet Explorer.) /* Steinar */ -- Homepage: http://www.sesse.net/
