I list my disk

root@emma [~]# df -Th
Filesystem    Type    Size  Used Avail Use% Mounted on
/dev/sda5     ext3    7.8G  638M  6.8G   9% /
/dev/sda8     ext3     39G  4.8G   32G  14% /home
/dev/sda6     ext3    996M   36M  909M   4% /tmp
/dev/sda3     ext3    7.8G  6.6G  768M  90% /usr
/dev/sda2     ext3    9.7G 1004M  8.3G  11% /var
/dev/sda1     ext3    122M   17M  100M  14% /boot
tmpfs        tmpfs   1014M     0 1014M   0% /dev/shm
/dev/sdb1     ext3     67G  294M   63G   1% /opt/cdp-server

then show disk use for /usr

root@emma [~]# du -sh /usr
3.4G	/usr
root@emma [~]#

So, how can i fix this little problem?
