No one expected that on December 31, Eduard Shishkin (developer and maintainer of ReiserFS 4) announces new version of one of the fastest file systems for Linux - RaiserFS 5.
The fifth version brings a new method of grouping block devices into logical volumes.
I believe that this is a qualitatively new level in the development of file systems (and operating systems) - local volumes with parallel scaling.
Reiser5 does not implement its own block level, such as in ZFS, but is implemented by means of the file system. The new "Fiber-Striping" data distribution algorithm will make it possible to more effectively arrange a logical volume from devices of different sizes and with different throughputs, in contrast to the traditional combination of a file system and RAID / LVM.
This and other features of the new version of Reiser5 should provide it with a higher level of performance compared to Reiser4.
The patch for the Linux kernel 5.4.6 can be found at SourceForge.
Updated utility Reiser4Progs with initial support for Reiser 5 in the same place.
