we have one of those? --Jimbo 00:21, 24 Jul 2005 (EDT)

we do now --Dave 01:53, 24 Jul 2005 (EDT)

also,

shouldn't the sed line be "sed s/ad0/mirror\/gm0/g /mnt/etc/fstab > /mnt/etc/fstab.new" instead? (i'd also recommend doing a diff between the fstabs before just switching them, but if you're doing software raid, i guess it can be assumed that you're smart enough to do it or accept the risks)

Now we need to fix fstab to refer to the mirror, not to /dev/ad0 itself. You can either manually edit it using ee or vi and change 
all references to /dev/ad0? to /dev/mirror/gm0? - ie /dev/ad0s1b becomes /dev/mirror/gm0s1b - or you can use a sed command to do it 
for you:

# sed "s%ad0%mirror/gm0%" /mnt/etc/fstab > /mnt/etc/fstab.new
# mv /mnt/etc/fstab /mnt/etc/fstab.old
# mv /mnt/etc/fstab.new /mnt/etc/fstab
