I set up a dual booting OpenBSD/ubuntu (only for the audio, I swear!)
install. I made sure to have the Ubuntu installer make an ext2 data
partition for sharing. For some reason OpenBSd couldn't see the ext2
partition until I added it manually. I would like to know why.
Here's my fdisk:
$ fdisk sd0

I used the 'b' command to extend disklabel(8)'s idea of the OpenBSD
area, and then it let me add this:
n: 230532750 82043955 ext2fs
and dmesg for good measure:

root on sd0a swap on sd0b dump on sd0b
After adding partition 'n' I can mount and use my data drive fine. My
only guess was that I had too many partitions, but the FAQ says "up to
'p'") which is greater than 'n' so that's not it. So any ideas why
OpenBSD didn't pick up the data partition on it's own? If you look
closely you'll see that it picked up the ubuntu root drive (as sd0i)
which was also not within the original disklabel(8) "b" limits.
Thanks,
-Nick
