Hi Kaushal,

not so easy to suggest any further steps and some more information would
be handy. What does your server do? Like Dirk suggested are you having a
lot of small files like you have it on a news server? Is it real hardware
or a virtual machine you are running? What programs are running? Maybe

Have you rebootet your server? After a reboot do you have the same "lost"

I would try and use a command line to find all files bigger than 1 GB and
see what is there. Then I would generate a large tarball of your server
and copy this tarball to another server. Then I would extract this tarball
on the other computer and analyze it carefully! Like does it needs the
same space as on the original server.

Hope this helps,
