9.0 - Mount to root.. Sorted..
Hi all, As Warren Block mentioned: If there are no ada devices in /dev at all, I'd guess too much has been > removed from the custom kernel. > So I've checked my custom kernel config (based on GENERIC) & indeed made some changes to the [S]ATA disk section after which I rebuilt & installed the kernel again.. The difference now with previous was that I *was* able to boot in single-user mode, mount, label my disk with tunefs, update my /etc/fstab accordingly & managed to install the world as a final step to my upgrade.. Problem solved, many thanx for all the assistance..

Upgrade to 9.0 - Mount to root failed..
Hi Matthew, Thanx for the quick reply.. Can't get it to work though..

Mounting ufs:/dev/ad*a*2s1a i.o. from ufs:/dev/ad2s1a simply doesn't work because as I've put in my original post with # ls -l /dev/ad* it doesn't exist.. Only ad2,ad2s1 & ad2s1a do.. > One way to fix this is simply to type in the new boot device in the > loader and then edit /etc/fstab from single user mode > Which boot device..? I wish it was simple.. The preferred method nowadays is to label the partitions, so probably > tunefs(8) labelling would be the best choice to get you through > the 8.1 -> 9.0 reboot. ie. Create the label: > ># tunefs -L ROOT /dev/as2s1a > # man 8 tunefs: The tunefs can not be run on an active filesystem. To change an active filesystem it must be downgraded to read only or to unmounted.. [Which I've done with # mount -r -f..] # tunefs: /dev/ad2s1a: failed to write superblock.. I've updated the /etc/fstab with the ROOT label but I can't get the single-user mount nor the tunefs to work..

Upgrade to 9.0 - Mount to root failed..
Greetings all,
It's my 1st time on any of the FreeBSD lists & I'm fairly new to FreeBSD to
please bear with me..
So I've upgraded from 8.1 to 9.0 & now the system can't mount in single
user mode to go through the final step of installing the world..
# cvsup.. Done..
# make buildworld.. Done..
# make buildkernel.. Done..
# make installkernel.. Done..
# reboot in single user mode to install world.. Failed to mount to
/dev/ad2s1a.. {Yes, that *is* my HD}
I rebooted from the loader prompt with my old (GENERIC) kernel & came up
with the following..
peggy# ls -l /dev/ad*

I know there's many 'mount' problem discussions out there but I can't seem
to find out how to overcome this problem..
Many thanx in advance for any assistance..
