Disk > 100%

[Weaseal]

I just unzipped a backup to the same partition it once resided on:

$ df -h
Filesystem     Size    Used   Avail Capacity  Mounted on
/dev/ad8s1a    496M    266M    190M    58%    /
devfs          1.0K    1.0K      0B   100%    /dev
/dev/ad8s1e    496M     20K    456M     0%    /tmp
/dev/ad8s1f     95G    2.9G     84G     3%    /usr
/dev/ad8s1d    4.6G    102M    4.1G     2%    /var
/dev/ad6s1a    496M    297M    159M    65%    /mnt/freebsd
/dev/ad6s1f     95G     90G   -2.9G   103%    /mnt/freebsd/usr
/dev/ad6s1e    496M    4.0K    456M     0%    /mnt/freebsd/tmp
/dev/ad6s1d    4.6G    4.0K    4.2G     0%    /mnt/freebsd/var

Do I need to be concerned with that 103%? Was any data lost? Do I need to try, try again?
