Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

As you can see I have about 40gb free but it shows 100% usage. I thought it might be a locked file or something but I have tried lsof to look for anything that my be locked, I have also rebooted the server but still have had no luck!
If anyone could help me out that would be great! If you need anymore info please let me know.
Thank you very much for your response, If you wouldn't mind taking a look at the result of the command: tune2fs -l /dev/sda3 and helping me go through it.
From the below results it does look like its 5%, i will do a bit of google'in but if you wouldn't mind, is there any risk with having it at 1-2%?
Does having it at 5% mean that I can only use 95% of the drive?

If the system filled up completely, everything would come crashing down in a hurry, very very bad things would happen. The reserved blocks are used so that root still has somewhere to work if the filesystem fills up. 5% is an antiquated number from way back in the day when hard drives were much smaller, in my opinion it should have never been a percentage, but a fixed value of maybe 100MB-1GB.
These days, 5% is so ridiculously overkill that it's not even funny anymore, I always resize it to around 1GB after setting up a filesystem. You can do that with:
tune2fs -r 250000 /dev/sda3
Or you can keep it a percentage and just lower it to 1% using evo2's suggestion.

In any case, you should figure out why it 'filled up' and fix it, otherwise its only a matter of time before it fills the new space you have created.
I'd start by checking /var/log and the logrotate tool (/etc/logrotate.d dir) to see if its working properly (see /etc/cron.daily dir)
Absolutely agree (with Chris) - but 850 Gig of logs ?. I don't think so.
Seems like a good candidate for spinning off big consumers to separate partitions. That way the root can be left with some reserved allocation, and the data partitions can be set to zero to recover the space.
/home would be my guess as a good start.
