This is what OpManager tells me : Used Space : 2728 %

This is what i get if I run a df -h on my server that OpManager it checking

Filesystem                                                                 Size  Used Avail Use% Mounted on

/dev/mapper/VolGroup00-LogVol00                      1.6T   51G  1.5T   4% /

Anyone know what is wrong, seems to be the problem on all my Linux server (CentOS 5.3)

Monitoring using SSH on OpManger.
