I kind of wonder if you are trying to use up all of the cylinder's
because it never lets you have the whole disk. My system is as follow:

kent@opal$ df
Filesystem  1K-blocks     Used    Avail Capacity  Mounted on
/dev/ad0s3a     99183    35689    55560    39%    /
/dev/ad0s3f   1488607      151  1369368     0%    /tmp
/dev/ad0s3g  12043560  2201761  8878315    20%    /usr
/dev/ad0s3e    496111     5192   451231     1%    /var
procfs              4        4        0   100%    /proc
/dev/ad0s1    2096224   290272  1805952    14%    /mnt

It is just a squeak but I am past 12GB. I'm also using FreeBSD
4.0-Stable, which was installed from scratch. The ~15GB FreeBSD slice
was added after a 2GB Fat16 and a 3GB NTFS in an extended partition. I
assigned the partitions through /var by size and /usr was what was
left. The FreeBSD slice was based on using what was left on the 20GB
Maxtor.
