Find Big Files or Big Directories

[Maxime Alarie]

Du -ms reports 15GB used.


Du -m reports many times 12GB. And my disk  (224GB) is 83% full. There is nothing on this server except  in /var/ and du -ms /var  reports 34GB

There must be something I am not getting.

What makes you think that the df output is incorrect? That sda1 is 73%
full and sdb1 93% full?

What makes you think that the du output is incorrect?

The "binaries contains only the data folder" case repeats itself in
the following pairs - and it is not necessarily wrong because it
simply implies that .../server only contains default, .../binaries
only contains data, .../76/b4 only contains 4d, etc:
