Hello,

I was running FreeBSD 7.0-BETA4 on a Dell Poweredge 750 and tried to
use freebsd-update to upgrade to 7.0-RC1.  I have successfully used
freebsd-update before, e.g. (albeit a different machine)

http://taosecurity.blogspot.com/2007/11/updating-freebsd-70-beta2-to-70-beta3.html

I followed these steps on the Dell.

fetch http://www.daemonology.net/freebsd-update/freebsd-update-upgrade.tgz
tar -xf freebsd-update-upgrade.tgz
sh freebsd-update.sh -f freebsd-update.conf -r 7.0-RC1 upgrade
sh freebsd-update.sh -f freebsd-update.conf install
shutdown -r now

Upon rebooting I encountered this error:

Trying to mount root from ufs:/dev/ad2s1a

Manual root filesystem specification:
...edited...
mountroot>

If I issue the ? command I see

mountroot>?

List of GEOM managed disk devices:
 acd0 fd0

I verified by booting the BETA4 CD that ad2s1a is the right location
for the / partition.

I next tried installing RC1 using a CD, but it failed to find any hard drive.

I finished by reinstalling BETA4 from CD, which found the hard drive.

What info can I provide to help troubleshoot this problem?

Thank you,

Richard
