difference bettween size?

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"

Re: difference bettween size?

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.

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