Lub Linux ntaub ntawv System

 

This is a quick reference to the Linux file system.

The common file systems used on new Linux installations are:

  • Ext4
  • XFS

Ext4 tso cai rau cov ntsws thiab nthuav tagnrho, whereas XFS tsuas tso cai rau nthuav tagnrho.

 

Journalling

Ob leeg ext4 thiab xfs yog journalling ntaub ntawv systems uas txhais tau tias thaum uas sau ntawv / txuag cov ntaub ntawv mus rau ib tug 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.

 

Lwv thiab Editing ntaub ntawv

Linux tso cai rau rho tawm thiab kho kom raug cov ntaub ntawv qhib. 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 ntaub ntawv tshuab yog tsim los txo fragmentation kom txaus ntawm cov ntaub ntawv rau lub hard disk. 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.
