Engelschall's instructions at http://people.freebsd.org/~rse/mirror/ which involves using dump(8) to transfer the data onto the second disk once it's setup as a gmirror provider. I must admit I never thought back on those instructions because they work very well. It was only recently that I had to deal with older hardware for which I had to salvage some old 4Gb disk drives. So, if you don't mind, I would very much appreciate if you could share your documentation with me. In case you're interested, I can offer you a space on my website should you want to have them online.
