8.0 can't find/read label on da3 (7.2 OK)
John Marshall
to this morning's RELENG_8_0. FreeBSD 8.0 seems unable to discover the
filesystem on /dev/da3. The earlier discs (da0, da1, da2) on that
controller are fine.
If I boot 7.2-RELEASE from a live CD, bsdlabel happily reads the /da3s1
label, I can fsck the da3s1d UFS filesystem, and I can mount the
filesystem. If I boot 8.0, I lose the disc again.

This is probably a dangerous dedicated disk made on 7.x
I had this issue also and some member of the list gave me this hint:
!!!!!!!!!!!!!!DO MAKE A BACKUP OF YOUR DATA BEFORE DOING THIS FROM YOUR
7.2 INSTALL !!!!!!!!!!!!!!!!!!!
Is your disk in "dangerously dedicated" mode?
If yes, this is what I did (advised by marcel@)
dd if=/dev/zero of=/dev/ad1 oseek=1 bs=512 count=1
where /dev/ad1 is my device. You should see some messages from
GEOM_LABEL removing and assigning new labels.
This worked for me, i do not know if it will work for you.
Regards,
Johan Hendriks

Thank you Johan,
Yes, this disc was partitioned in "dedicated" mode. The above recipe
solved my problem.
It may be a good idea for somebody knowledgeable in this field to give
attention to the "Dedicated Mode" Section 18.3.2.2 of the Handbook if
this mode now unsupported.
