My FreeBSD 5.2.1 server had a 4.5 GB HDD. I decided to upgrade it
with a larger drive. I installed a new drive on the second IDE
channel which made it ad2, of course, my original drive was ad0. I
created a partition, boot loader and matching slices on the new
drive. Then I copied the old drive to the new drive using tar. Once
finished, I removed the original drive and installed the new one on
the primary channel. When I booted up everything appeared normal, but
when the system starts to mount "/" it gives no error or warning and
just drops to a "Manual mount root specification" prompt. If I type
"ufs:ad0s1a" it boots up and everything is perfect. This is the same
slice "/" was on the old drive as well.
I have tried the following with no success:
Checked /etc/fstab
boot0cfg -v -B ad0
bsdlabel -B ad0s1
tried booting from a cd, going into post install config, fdisk, and
set the partition as bootable, it already was.
Since upgrading the hard disk, I have upgraded the system to 5.5 and
then to 6.2. This system has been working great for over a week now,
just have this boot problem.

Here is my fstab:
/dev/ad0s1b none swap sw 0 0
/dev/ad0s1a / ufs rw 1 1

Output from bsdlabel

Could it be because your root partition is not at offset 0?

I don't think so, but I certainly could be wrong. Here is another system:
# bsdlabel ad0s1
# /dev/ad0s1:
8 partitions:
# size offset fstype [fsize bsize bps/cpg]
a: 18932866 137363456 4.2BSD 2048 16384 28552
b: 1048576 0 swap
c: 156296322 0 unused 0 0 # "raw" part,
don't edit
d: 62914560 1048576 4.2BSD 2048 16384 28552
e: 73400320 63963136 4.2BSD 2048 16384 28544
here s1a is not at offset 0, yet the system boots fine. I create the
swap partition first usually, hence the offset being 0 for swap.
