Le système de fichiers Linux


This is a quick reference to the Linux file system.

The common file systems used on new Linux installations are:

  • EXT4
  • XFS

Ext4 permet de réduire et augmenter les volumes, tandis XFS ne permet d'étendre les volumes.



Les deux ext4 et XFS sont journalisation des systèmes de fichiers qui signifie que lorsque l'écriture / enregistrement de fichiers sur un disque, the file system will save somewhere else temporarily until the full file has been successfully saved. It makes a log of the status of the write and will complete save operations by checking the log. This approach cuts down on corrupted files.


Suppression et modification de fichiers

Linux permet de supprimer et modifier des fichiers ouverts. This is done by still linking the files to the OS even if it deleted. You can also move files whilst being partially downloaded or delete programs that are currently running without crashing.



Les systèmes de fichiers de Linux sont conçus pour minimiser la fragmentation en gardant suffisamment d'espace entre les fichiers sur le disque dur. This allows files to grow and still be written to the same location on the hard disk. Overtime though the file system can become fragmented where tools are provided for de-fragmentation.
