I think you may have misunderstood the question. I think that Evan is misunderstanding how Vinum works, and he wants to overlay an existing /usr slice under Vinum. There's a description of how to do that at http://www.vinumvm.org/cfbsd/vinum.pdf. >> If i do this will i be able to access all the files on the first >> hard drive as though it was just a regular partition. Well, you can't access files on a partition. You access files from a file system, whether it's on a partition, a Vinum volume or elsewhere (vnode device, for example). That's the purpose of mount. Once you have mounted your file system, it doesn't make much difference where it's stored. Greg -- Note: I discard all HTML mail unseen. Finger grog@FreeBSD.org for PGP public key.
