This happens mostly when some one delete a file which is opened by a running process..Although the file was technically removed from the filesystem, the disk space will not be freed if other process(es) have the same file open. As soon as there are no active processes which have
this file open, the disk space will be freed.

If you have any clue about recently deleted files consumig large space in the partition,you can look for that process accessing that file and terminate /restart the same. Or else commands below will help...

Find processes which have files open in the file system

# fuser -c /

List might be long, but you have to narrow down the list by verifying suspect process using ptreee command and terminate / restart the same to free up space.Be careful on this step,ensure that you are not operating on the wrong process.. :-)
