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 võimaldab kahaneb ja laiendada mahud, samas XFS ainult võimaldab laiendada mahud.

 

Journalling

Mõlemad ext4 ja xfs on journalling failisüsteeme, mis tähendab, kui kirjutad / failide salvestamisel kettale, 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.

 

Kustutamine ja redigeerimine Files

Linux võimaldab kustutada ja redigeerida faile avada. 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.

 

Killustatus

Linux failisüsteemi eesmärk on vähendada killustatust hoides piisavalt ruumi vahel faile kõvakettale. 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.
