The Linux File System

 

This is a quick reference to the Linux file system.

The common file systems used on new Linux installations are:

  • EXT4
  • XFS

Ext4-enye ohere ka ịda mbà na mụbaa mpịakọta, ebe XFS nanị na-enye ohere mụbaa mpịakọta.

 

Journalling

Ma ext4 na xfs na-journalling faịlụ usoro nke pụtara mgbe ede / azọpụta faịlụ ka a disk, 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.

 

Ihichapụ na-edezi Files

Linux na-enye ohere ka ihichapụ ma dezie emeghe faịlụ. 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.

 

Fragmentation

Linux faịlụ usoro na-e na-ebelata fragmentation site n'idebe zuru ezu ohere n'etiti faịlụ na diski ike. 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.
