This article is to share with you about which file systems are commonly used in Linux, the editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article. Let's take a look at it with the editor.

1. Linux operating system uses virtual file system (VFS) up and user process file access system call interface, down and specific different file system implementation interface. VFS shields the implementation details of specific files and provides a unified operation interface. Arbitrary file systems can be implemented through VFS, and these file systems can be accessed through file access system calls. Therefore, the Linux system core can support more than ten file system types, such as Btrfs, JFS, ReiserFS, ext, ext2, ext3, ext4, ISO9660, XFS, Minx, MSDOS, UMSDOS, VFAT, NTFS, HPFS, NFS, SMB, SysV, PROC and so on. Several important file systems that it supports are described below

2. Ext is the first file system specially designed for Linux and made for linux core. Maximum limit for a single file: unknown; the file system supports the maximum capacity of 2GB.

3. Ext2 is designed by R é my Card to replace ext and is the file system used by the LINUX kernel. The maximum limit for a single file is 2TB; the file system supports the maximum capacity of 32TB.

4. Ext3 a journaling file system. The maximum limit for a single file is 16TB, which supports the maximum capacity of 32TB.

5. The development team led by ext4Theodore Tso realizes the log file system under the Linux system. The maximum limit for a single file is 16TB, which supports the maximum capacity of 1EB.

6. JFS2 is a byte-level log file system, which is mainly designed and developed to meet the high throughput and reliability requirements of the server. The maximum limit for a single file is 16TB, which supports the maximum capacity of 1PB.

Note: only the maximum file size limits and maximum file system capacity of these file systems are described here, not their performance comparison.

The above are the common file systems in Linux, and the editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
