Hi Everyone,

I have installed FreeBSD 6.2-RELEASE amd64 on a new boxen... and just  
realized that I am missing just a 'little' bit of storage space ;)

The raid array is as follows:

3ware 9650SE-8LPML Controller
1 x 76GB OS RAID 1 Array (2 x 80GB drives)
1 x 3.4TB DATA RAID 5 Array (6 x 700GB drives)

In order for FreeBSD to even see the controller, I had to download  
the 3rd party drivers from the 3ware site and follow their  
instructions. The installation went very smoothly, I could clearly  
see the 1 x 76GB array & the 3.4TB array, which I successfully  
partitioned and labeled in the FreeBSD setup. I was required to  
recompile the kernel post installation so that FreeBSD would continue  
to see the array. There seemed to be no issues during any of the  
installation/post installation compile.

However now it appears that I am missing a fair bit of space... or it  
is not reading correctly, I don't know exactly. This is the first  
time I have worked with volumes this large, certainly in FreeBSD.

devfs                1        1          0   100%    /var/named/dev

As you can see /db is reading as 1.2T, whereas during the  
installation partition/label process this was at ~ 3.4T, which is  
what I am expecting. If anyone could provide some input as to where  
the rest has gone that would be greatly appreciated!
