The fdisk step does not work for me using the 8.1 memstick. It looks as if I may have reached a dead end, but can anyone identify where I missed a turn? History, all in http://lists.freebsd.org/pipermail/freebsd-questions/2010-September 221253.html, 221275.html, 221283.html, 221501.html, 221672.html Details of the latest attempt: I've created the gmirror (which currently contains only one provider -- the other is to be added later), and Fixit can see /dev/mirror/gm0* once I've executed "gmirror load", but neither gpart nor fdisk seems to recognize gm0 as something on which it can operate. The following is a script(1) starting when I first boot into Fixit# from a memstick. I've inserted a blank line ahead of each command to simplify skipping over output that may not be relevant, and I've inserted some commentary (lines starting with !). The disk already contains the gmirror metadata (created during a previous attempt). Script started on Mon Oct 4 03:42:54 2010 Fixit# dmesg Copyright (c) 1992-2010 The FreeBSD Project.
