Broken FreeBSD 9.0 after freebsd-update

J

I updated a fresh install of FreeBSD 9.0(ZFS mirror root) using freebsd-update fetch and freebsd-update install and then rebooted

During reboot my system hung on 'All buffers synced'

After a hard reboot, my system fails to boot

I am new to FreeBSD and cannot find any information on rescuing an install which fails to boot

So far, I have booted in shell on the live cd and:
- mounted zroot
- re-added /boot/loader.conf
--> added lines:
Code: 
zfs_load="YES"
vfs.root.mountfrom="zfs:zroot"
I also checked /etc/rc.conf but that looks unchanged since update
I reset the mountpoints which seemed like something I should do since thats what was done during install
Code: 
zfs umount -af
zfs set mountpoint=legacy zroot
zfs set mountpoint=/tmp zroot/tmp
zfs set mountpoint=/usr zroot/usr
zfs set mountpoint=/var zroot/var
I am not sure if I should also be re-adding the bootcode to the boot partitions?

I didn't think an update would change any of that?

Could someone please give me some tips on how to rescue my system, or at least point me at some relevant documentation. I obviously can reinstall as this is just a fresh install, but understanding how to rescue a broken install would be vastly more valuable to me if I am going to continue to use FreeBSD.

Thanks,

JG
 
"Fails to boot". Can you please be more specific. What error are you getting?

My BIOS says there is no boot device. Asks me to insert one or reboot.

However, I had rebooted twice with no issue before running freebsd-update.

Nothing else other than running freebsd-update has changed as far as I can tell.

BTW, removing 'world' from Components in /etc/freebsd-update.conf will cure this problem according to PR:PR 172086

I have posted in that thread.

My problem is that I don't actually know how to fix my FreeBSD install which now fails to boot.

Are you saying I should use a live environment and change that and re-run freebsd-update while chrooted or something?

Again, excuse my newness. I am not very experienced with FreeBSD.

Is the disk still being detected by the BIOS?
