You have to use the Offset for the chunks after the first to "jump" beyond the already existing chunks in that raw device. But: The sum of offset + size must be less than 2GB. So, normally you will have to use several raw devices. -- Helmut Leininger Bull AG / Vienna Unix Support Email: Helmut.Leininger@bull.net This opinion is mine and not necessarily that of my employer.
