Why would du and df show different free space on a filesystem?

Why would du and df show different free space on a filesystem?

du is used to estimate file space usage—space used under a particular directory or files on a file system. df is used to display the amount of available disk space for file systems on which the invoking user has appropriate read access. The result of the command du doesn’t include the size of the deleting file.

Why does df show bigger disk usage than du?

What is most likely happening is that a process is running which is holding open a file which has been deleted. df thinks that the partition is full since the inodes are all taken up by that process. This often happens when a service such as samba has filled up the log file.

Why is space not being freed from disk after deleting a file in Ubuntu?

The other answers are correct: If you delete a file, and space does not get freed, it’s usually either because the file is still kept open, or there are other hardlinks to it. That way, you’ll quickly find files that still occupy space because of a second hardlink.

Is df or du more accurate?

df vs. du. The (very complicated) answer can be best summarized like this: The df command provides a sweeping ballpark figure for how much space is being utilized on your filesystem as a whole. The du command is a much more accurate snapshot of a given directory or subdirectory.
