difference bettween size?

[taouw]

hi,
can anyone help me to see the real size that i have:
I have 1 logical volume (/dev/vg00/lvol2):
total 78460135KB (78GB)
free allocated 4377680kb (4GB)
used allocated 74082455kb (74GB)
95% allocated used
this logical volume is mounted in /hf

but when i check files in /hf directory; i found the following:
only one directory /data
/hf/data/12.u001 (0.5GB)
/hf/data/13.u001 (1GB)
/hf/data/14.u001 (0.5GB)

the total size is 2 GB

why there is a difference between 74 GB and 2 GB allocated in hf directory? and how can i check the real used space?
is there any hidden file or no????
is there any way to find what is hapening to 72 GB allocated "the difference"

Typically this is cause by deleting a file that is still in use by a process.

Will need to stop and restart the process that still has the file(s) open.

lsof can help to find open files in filesystems.

can y please check the following steps, it is wrong or right ????

# fuser -u /hf

#kill -9 idprocess # to Kill all processes with files

but what is the difference between this method and lsof method ???????

fuser is only about 50% accurate in identifying all open files. lsof is the most accurate way to find all open files.
