Cloning a complete HD mbr and all to second HD in same FreeBSD box is a snap using ghost. That's the way I make additional FreeBSD workstation pc'a. I take the HD from the target and plug it into the FreeBSD box, then boot ghost from floppy, do ghost hd to hd copy, remove cloned HD and put it into target box and boot it up and it runs just like the original. This is not the Freebsd way. But its quick and can also be used for my window boxs on my LAN. You get double the bang for your buck. -----Original Message----- From: owner-freebsd-questions@freebsd.org [mailto:owner-freebsd-questions@freebsd.org]On Behalf Of Joe Auty Sent: Tuesday, February 14, 2006 12:26 PM To: Alec Berryman Cc: freebsd-questions@freebsd.org Subject: Re: best approach to clone a disk?

I've never had to do that... basically, I just need something that will allow me to boot up into single user mode. I've been using the source disk in single user mode, and doing a mount -u / to make sure that it is mounted read only. Before I go this route, I'm thinking it might be wise to give "dump" another try from a working boot CD. What is the best way to create myself a boot CD that I can use to boot up in single user mode? As far as your tar idea, the idea seems great, although I'm not sure whether I have enough space to store both the tarball and the space needed to extract the tarball to. We are talking over a 100 gig here.
