In 2003, XFS was ported to the Linux kernel by Steve Lord and saw its first inclusion into a Linux distribution in 2001. As Linux began to gain enterprise clout throughout the 1990s, it was clear that SGI should make their file system available to the up-and-coming UNIX competitor. The main goal? High performance, high reliability, and better parallel performance. (SGI), XFS was originally conceived for SGI’s own commercial UNIX variant, IRIX, in 1993. ![]() Initially developed by yesteryear’s tech megalith, Silicon Graphics Inc. (Credit: Darel Parker on ) X File System (XFS) I think it is pretty safe to say that this file system will be around for a very long time! The original Silicon Graphics (SGI) logo. Today, ext4 is still the most popular Linux file system, even above more advanced kinds, like Btrfs or ZFS. However, even with newer versions of the file system family, all three are still used in different situations today, though ext4 is recommended for most use cases. With these new improvements, ext2 quickly became a household name for early Linux adopters.Īs the years rolled on, an extraordinary amount of work was put into the next iterations of the Extended File System family, ext3 and ext4. In order to fix the problems with ext, T’so began working on ext2, which drew a lot of inspiration from the Berkeley Fast File System (also known as, the Unix File System or UFS), which was utilized in many different Unix and BSD operating systems (and still is today in the case of BSD). Though ext fixed the limitations of the MINIX file system, it contained other problems like the lack of support for separate timestamps according to file access, inode modification, or data modification. However, the way that ext was built gave rise to a whole bunch of other issues compared to the MINIX file system. ext became the very first file system to utilize the Virtual File System (VFS) layer in the Linux kernel–which is an extremely important aspect of the kernel that allows so many different file systems to work with it. The first attempt by T’so was the original Extended File System (ext). However, the MINIX file system ran into a bunch of limitations and many of the early kernel developers had laid out plans to replace it very early on. In the beginning, the early versions of Linux used a modified version of the MINIX 1 file system. Though even T’so himself has said that ext4 isn’t the future of file systems–those rights are reserved for the likes of Btrfs or ZFS–what functionalities ext4 lacks it more than makes up for in pure speed and reliability. This is because ext4 is the default file system for the vast majority of Linux distributions on the planet. If you have installed a Linux distribution with the default settings in the installer, chances are extremely high that you’ve been using ext4 all along without even knowing it. This feature allows for users to retain data in the event of a crash or unexpected shutdown. Developed by long-time Linux kernel developer, Theodore Ts’o, ext4 was introduced as stable in October 2008, using speedy linked lists and hashed B-Trees as the base data structure.Įxt4 is what is known as a journaling file system, which means that it uses a “journal” (usually a circular log) to record the intentions of changes that are not yet committed to the file system. ext4 is the latest generation of the Extended File System family, with both ext2 and ext3 being used heavily prior (and even still today in some instances). The ext4 file system is without a doubt the most popular choice for file storage in the Linux (especially, desktop) world. We’ll take a look at a few of the most popular file systems in use today as well as an up-and-coming file system that I’ve had my eye on for quite a while! Extended File System, version 4 (ext4) There are a vast array of file systems available to use with the Linux kernel today but there are really only a few that see heavy usage from the Linux community.
