OK. Based on this you can just do the bsdlabel -e /dev/mirror/gm0s1
as root (or from the fixit) and then, right after the definition of
the 'f:' partition make an 'h:' partition with '*' as both size and offset.
eg.
h: * * 4.2BSD 2048 16384 28528
Write and exit from the edit session and then newfs the new partition
and fix up your /etc/fstab - the real one, not the fixit one
so it will mount where you want it - don't forget to make the mount point.
It should work just fine.
Note, that when you are running from the fixit, it makes a filesystem
in memory and mounts that as root (/). Your real root from the disk
will probably be in /dev/mirror/gm0s1a so you will need to make
a mount point in the memory root, let's say /tmproot and mount to
that and then edit that fstab. eg
Boot from fixit - get that holographic shell going
bsdlabel -e /dev/mirror/gm0s1
Do the editing, write and quit
mkdir /tmproot
mount -w /dev/mirror/gm0s1a /tmproot
cd /tmproot/etc
vi fstab
fix it up, write and quit
Pull the CD, reboot and things should be just fine.
My only concern is, I have never used the fixit on a mirror.
I presume it should look just the same, but who knows, it might
have a different looking address. I hope the gmirror stuff
works on the fixit. If not, you will need to make a boot on
something else - another hard disk with a full system.
