How do i check this issue and fix it.
how do i find out and why suddenly showing this much of increasing the size of hard disk.
Could anyone help me
Basically, df reads the superblock only and trusts it completely. du reads each object and sums them up.
Any running process can keep a deleted file open. This means the space will still be reserved and seen by df, but since du will no longer see a reference to that file in the directory tree, it cannot see those reserved blocks.
Try to see the number of open file which could be causing the problem.
