[dba-Tech] A new file system

[Jim Lawrence]

Hi All:

There are dozens of file systems in both the Windows and Linux world. Each one is either kept for a while, rejected finally or holds some particular purpose.

Microsoft Windows OS uses two major file systems: FAT, inherited from old DOS with its later extension FAT32, and widely-used NTFS file systems. Recently released is ReFS file system (the Resilient File System) was developed by Microsoft as a new generation file system for Windows 8 Servers.

Linux, of course, supports numerous file systems, but common choices for the system disk on a block device include the ext* family (ext2, ext3 and ext4), XFS, JFS, ReiserFS, ZFS and btrfs...to name a few. (There are supposedly somewhere between 50 and a hundred file systems that are available in the Linux/Unix sphere but many are specific to particular hardware and software environments.) 

Recently, a new Linux file system is trying to become a first-class citizen by being built into next Linux kernel called the Bcachefs filesystem:
