I guess that means that the lvmutils (even the patched version in the RPM) are heavily broken ... Andrea, could you send me the patches you use to make your LVM utilities work? Then we'll be able to put together at least one working LVM utilities version ;) Heinz, how about releasing a 0.8.1 version of the utilities so that there is something WORKING out there? Not having working LVM utilities available is an utter disgrace when all the code to make it work is just available... regards, Rik -- "What you're running that piece of shit Gnome?!?!" -- Miguel de Icaza, UKUUG 2000 http://www.conectiva.com/ http://www.surriel.com/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
