ການ​ລະ​ບົບ​ໄຟ Linux

 

This is a quick reference to the Linux file system.

The common file systems used on new Linux installations are:

  • EXT4
  • XFS

Ext4 ອະ​ນຸ​ຍາດ​ໃຫ້​ໃຫ້​ນ້ອຍ​ລົງ​ແລະ​ຂະ​ຫຍາຍ​ປະ​ລິ​ມານ​ການ, ໃນ​ຂະ​ນະ​ທີ່ XFS ພຽງ​ແຕ່​ອະ​ນຸ​ຍາດ​ໃຫ້​ຂະ​ຫຍາຍ​ປະ​ລິ​ມານ​ການ.

 

ວາ​ລະ​ສານ​ການ

ທັງ​ສອງ ext4 ແລະ XFS ແມ່ນ journalling ລະ​ບົບ​ໄຟລ​໌​ທີ່​ມີ​ຄວາມ​ຫມາຍ​ໃນ​ເວ​ລາ​ທີ່​ລາຍ​ລັກ​ອັກ​ສອນ / ການ​ປະ​ຢັດ​ໄຟລ​໌​ກັບ​ແຜ່ນ, 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.

 

ລຶບ​ແລະ​ດັດ​ແກ້​ໄຟລ​໌

Linux ອະ​ນຸ​ຍາດ​ໃຫ້​ການ​ລຶບ​ແລະ​ດັດ​ແກ້​ໄຟລ​໌​ເປີດ. 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.

 

ການ​ກະ​ຈາຍ

ລະ​ບົບ Linux ໄຟ​ໄດ້​ຖືກ​ອອກ​ແບບ​ເພື່ອ​ຫຼຸດ​ຜ່ອນ​ການ fragmentation ໂດຍ​ການ​ຮັກ​ສາ​ພື້ນ​ທີ່​ພຽງ​ພໍ​ລະ​ຫວ່າງ​ໄຟລ​໌​ໃນ​ແຜ່ນ​ແຂງ​ໄດ້. 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.
