What are the file systems supported by linux?

The file systems supported by Linux are: Btrfs, JFS, ReiserFS, ext, ext2, ext3, ext4, ISO9660, XFS, Minx, MSDOS, UMSDOS, VFAT, NTFS, HPFS, NFS, SMB, SysV, PROC wait.

#The operating environment of this tutorial: Red Hat Enterprise Linux 6.1 system, Dell G3 computer.

The Linux operating system uses the virtual file system (VFS) to interface with the user process file access system call upwards and downwards with the implementation interfaces of different specific file systems. VFS shields the implementation details of specific files and provides a unified operation interface upwards.

Any file system 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 etc.

The following describes several important file systems it supports

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

3. ext2 was designed by Rémy 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 a maximum capacity of 32TB.

4. ext3 is a log file system. The maximum limit for a single file is 16TB, and the file system supports a maximum capacity of 32TB.

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

6. JFS2 is a byte-level log file system. This file system 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, and the file system supports a maximum capacity of 1PB.

Note: This only describes the maximum file size limit and the maximum capacity of the file system for these file systems, and does not explain their performance. Compare situations.
