==================
Linux文件系统选择
==================

概要
======

参考 `XFS vs. Ext4: Which Linux File System Is Better? <https://blog.purestorage.com/purely-educational/xfs-vs-ext4-which-linux-file-system-is-better/>`_ :

- XFS对于大型文件性能更好: 支持大型文件的并发读写操作，例如媒体文件，数据库文件性能更好，适合需要高响应性能的服务器
- EXT4对于海量小型文件性能更优(但不支持并发读写操纵)，所以操作系统根分区建议采用，也适合小型文件共享
- EXT4提供了较好的安全属性设置
- XFS内建了恢复工具，而EXT4则需要使用第三法国恢复工具
- XFS和EXT4都经过了长期的高负载考验，所以通常并没有明显差异，仅在高压力服务器上需要谨慎区分选择
