newfs error

[Corry Andrew Lazarowitz]

I am relativily new to FreeBSD in comparison to most out there (Been going for about a year and a half now) so this may be a dumb question.  I got my brothers Imac booting from my FreeBSD server, and get into single user mode.  When I try and newfs /dev/ad0s9 I get a lot of stuff, here's the gist of it

I believe it first prints what it is going to do as far as reading the secotrs, setting a block size, etc.  
Then it prints out suber-block backups (for fsck -b #) at:
then it lists a long set of long numbers
Finially, it says 
newfs: Cannot retrieve operator gid

I tried searching the internet all over, FreeBSD, NetBSD, OpenBSD, even linux stuff, I couldn't find anything with operator gid and newfs.  I am guessing this is probably because of 1 of 2 things:
1 no one has had this issue before.  Not likely
2 Its a real simple problem, or I am doing that SHOULD be obviously wrong, but alas, I can't see it.

Any help is appreciated!
Thanks
