There were a couple things that caused some head-scratching. 1. I read somewhere that it's safest to resize the filesystems on the existing drive before doing anything else, to allow for a 4K superblock beginning on a 64k boundary at the end of the partition. I did that. (Straightforward instructions at http://lists.centos.org/pipermail/centos/2006-April/063687.html) 2. In part 2, page 7, there is a step "Next replace LABEL=/boot with /dev/md0 and LABEL=/ with /dev/md2 in /etc/mtab" that I kinda questioned. It was my understanding that /etc/mtab is maintained by the mount command. (From man mount: "The programs mount and umount maintain a list of currently mounted file systems in the file /etc/mtab".) This makes the command on page 9, "cp -dpRx / /mnt/md2" *appear* to be copying md2 to itself. Confusion aside, the command has the desired result. Aside from those 2 points, it went very smoothly.
