UFS, by default, reserves 8% of space for use by root, and only root.
`df' does not show this space. So if the FS was full, `df' would say it
was 108% full.
To change this percentage, run:
# tunefs -m NEW-PERCENT
Note that it is not advisable to change it below 8%, as this will cause the
kernel to change the optimization level and make stuff slower.

Basically, don't worry, all your space is there.
