The procedure shown there produces a mirror that will not boot on FreeBSD
9.
no idea but my procedure certainly would work if you use installer
1) install to first disk
2) gmirror label system /dev/seconddisk
3) bsdlabel -w /dev/mirror/system
4) bsdlabel -e /dev/mirror/system - make partitions as required.
5) bsdlabel -B /dev/mirror/system
6) newfs all created partitions (/dev/mirror/systema etc...)
7) add
vfs.root.mountfrom="ufs:mirror/systema"
to loader.conf
edit /etc/fstab and change all things to new places
8) mount and copy files using tar or dump/restore to new place
9) reboot. system will start from gmirror
10) gmirror insert system /dev/firstdisk
all done.
if installer is not used but bootable media with complete system, just create
gmirror then as usual.
The current Handbook procedure avoids the copy by using the existing
disk as-is and just writing the gmirror metadata to the last block. If
that last block is already part of an MBR partition, the more strict
checking stops booting in 9.0.
