Clean files

I tested to install lustre file system, but then noticed that the disk space is not large enough to compile source (10G with vbox). Then I remove some lustre related files; however, I notice that the original file system (ext) is still occopied by something.

Code:

/dev/sda1             9.4G  7.1G  1.9G  80% /

However, checking with find command

Code:

find / -type f -size +50M -exec ls -alh  {} \;

shows

Code:

-rw-r--r-- 1 root root 73M Aug 27 20:45 /usr/src/linux-source-3.0.0.tar.bz2
-r-------- 1 root root 1018M Nov 14 19:13 /proc/kcore
find: `/proc/1985/task/1985/fd/5': No such file or directory
find: `/proc/1985/task/1985/fdinfo/5': No such file or directory
find: `/proc/1985/fd/5': No such file or directory
find: `/proc/1985/fdinfo/5': No such file or directory
-rw-r--r-- 1 user user 1.9G Sep 16 15:16 /home/user/important.file

Sum up with the files larger than 50M, still there are around 3-4G missing. How can I make sure what files/ process consume large space? And release them?

Thanks.

Code:

find / -type f -size +50M -exec ls -lh {} \; | awk '{ print $9 ": " $5 }'

or

Code:

#find / -size +50M -exec du -h {} \;
