defrag

[Scott(0)]

Assuming you have an ext4 file system, one method to defrag would be to use the command

Code:

e4defrag

The -c option will generate a fragmentation score and let you know if defragging is necessary.

Example, get a fragmentation score for the root file system

Code:

sudo e4defrag -c /

Example, defrag file system starting a root

Code:

sudo e4defrag /

The source article below will give more information and examples.
