As far as I do know there is only one way to do what you want: 1. Backup your partition to an external disk using the "dump" command. 2. Boot your computer from a Live-CD and delete that particular partition. 3. Make a smaller partition using "bsdlabel" and mount it. 4. Restore your data in the new and smaller partition using the named command "restore". This seems to be a hard work, but AFAIK is the only way in FBSD to resize a partition to a smaller amount. Greetings Frank
