![]() ![]() ReiserFS has a unique (and by default enabled) ability to optimize disk space occupied by small files (less than one block) (and it should be remembered that in any UNIX system such data are present in abundance). Therefore, we will only consider Reiser3’s capabilities. However, after the arrest of the manager, Hans Reiser, the development of the file system has slowed down, and the new version is still not included in the kernel. It has added encryption, improved performance, and much more. It’s Reiser3 or as it is called ReiserFS and the new version Reiser4. ![]() It reduces the space they take.Īt the moment, there are two stable versions of the file system. This file system allows you to place small files and file tails in one block. But its disadvantage is that you cannot use background encryption. And the most important thing is that ReiserFS can be used as the main file system for the root, as well as Ext4. It is faster than Ext4 family file systems. In addition, the file system supports fast rebuilding of its tree and has extensive recovery capabilities. The maximum file size is 1 exabyte and the number of files that can be found on a single partition is about four billion. The file system structure is based on trees. ReiserFS is an efficient file system that works very quickly with small files and supports journaling for fast recovery in case of problems. It was the first journaled file system that was accepted into the kernel and developed when Ext file systems were not yet planned. The ReiserFS file system was developed especially for the Linux operating system by Hans Reiser and Namesys company.
