• The Design of Reiser4

    The design and implementation of the reiser4 file system... Despite the name, this filesystem is written from scratch, although it inherited some features of its “ideological” predecessor – reiserfs. In addition to the traditional Linux fs functions, reiser4 features: transparent compression and encryption of files, full data journaling [], and almost unlimited extensibility, i.e. the ability to adapt to arbitrarily complex end user requirements. On modern machines equipped with fast processors and large amounts of RAM, data compression does not degrade, but on the contrary – increases the performance of the file system, because data conversion is performed relatively quickly, and the volume of disk traffic is reduced. more »

    After using AMD Epyc-hearted beast with reiser4 I don't want to use anything Intel again! We aren’t for slowing down… To add some further icing to the cake then the AMD EPYC™ platform also offers significant performance benefits when the mitigations for the aforementioned Meltdown and Foreshadow threats are applied, namely AMD does not currently believe to be affected by them... more »

  • Xochiquetzal: fsck.reiser4 --fix ∙ Upgrading From Prior Reiser4 Software Format Release Number (SFRN).

    as I built VirtualBox 6.0.8 from source in my Debian -based AMD64 Metztli Reiser4 development environment, I came across pre- Linux kernel 4.14.x virtual machines which had been formatted in Software Format Release Number (SFRN) 4.0.1. It is important to remember reiser4 in the context of in Linux kernel 4.14... more »
