Hi,

are you sure, no one (program, daemon, human being) is using any  
deleted files?

If you are not sure consider a shutdown of all services or eventually  
a complete reboot.

> Please suggest further

Your blocksize is 4096, so regardless of the size of the file it will  
use at minimum 4k.

If you want to take the effort you can check for wasted space.

For example
find /home /usr  -size -4096c | wc -l
shows you a count of files which are smaller than 4096 bytes.

Cheers

Dirk
