HOWTO : FreeNAS 8.0.3 RELEASE p1 USB device boot bug fix

The Problem

When I upgraded my FreeNAS to the latest version FreeNAS 8.0.3 RELEASE p1, it refused to boot and stop at the following message.

mountroot> GEOM: da0s1: geometry does not match label (16h,63s != 255h,63s).
GEOM: da0s2: geometry does not match label (16h,63s != 255h,63s).

I typed the following command and it boots fine.

ufs:/dev/da0s1a

The problem is that I need to type the captioned command on each boot up. How to solve this problem? Yes, I can.

The Solution

After the system is booting up and a menu is displayed. Select "9) Shell" to go to the shell prompt where we can do the following.

Step 1 :

nano /etc/fstab

Change from :
/dev/ufs/FreeNASs1a / ufs ro 1 1

To :
/dev/ufs/FreeNASs1a / ufs rw 1 1

Step 2 :

Then, save and exit the editor. Execute the following command :

mount -a

Step 3 :

Next, open up another file :

nano /boot/loader.conf

Change from :
#Fix booting from USB device bug
kern.cam.boot_delay=10000

To :
#Fix booting from USB device bug
kern.cam.boot_delay=20000

Save and exit the editor. Then reboot. This time, the boot up is much slower than before but it works. Problem solved!

That's all! See you.
