Anything in dmesg or /var/log/messages. I have checked many times and can't find anything different about that FS compared with the others. It isn't a misspelling because there isn't anything in /dev/ufs except the other 4 labels that I am already using. There is nothing in the logs except the boot error in dmesg when it couldn't find /usr to mount it. The system works so I am not really worried about it.

The labels are removed when the partition is mounted somewhere! So, you will only see the labels of unmounted partitions/disks in devfs. See for yourself (commands run on my 8.0-RELEASE-p2 system): Checking that this partition is labeled; # tunefs -p /dev/ad6s1a ... tunefs: volume label: (-L) rootbk When it is mounted, # mount ... /dev/ad6s1a on /mnt/bk/root (ufs, local) there are no labels: # ls /dev/ufs/* /dev/ufsid/* ls: No match. After unmounting # umount /dev/ad6s1a # ls /dev/ufs/* /dev/ufsid/* /dev/ufs/rootbk /dev/ufsid/482e0880cf225c60 Both the label set with tunefs and the ufsid label appear! Mount it again and the labels disappear again; # mount /mnt/bk/root # ls /dev/ufs/* /dev/ufsid/* ls: No match. Hope this helps.

I know I had trouble installing 8.0 on a drive that previously had 6.2 installed on it. Something about the MBR support in 8.0 was different and the labels from 6.2 were invisible to it. So when it came time for disklabel to write out the labels during the 8.0 install it would fail. This is what I did: Boot from a LiveFS CD and execute: sysctl kern.geom.debugflags=16 dd if=/dev/zero of=/dev/adx oseek=1 bs=512 count=1 Replace 'x' in adx with your drive number. If your problem is being caused by the same situation I experienced this should take care of it. Do I am missing something? On my other machine it prints a lot of GEOM: ad2s1a: geometry does not match label (255h,63s != 16h,255s). GEOM: ad2s1c: geometry does not match label (255h,63s != 16h,255s). GEOM: ad2s1: geometry does not match label (255h,63s != 16h,255s). For the most part simply ignore these. Lots of people see them nowadays and considered to be cosmetic and harmless. I believe it has something to do the drift away from the old MBR DOS compatibility days and the move to newer slicing/partitioning schemes. In other words these will eventually disappear, but in the meantime are probably a red herring. -Mike ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
