No one expected that on December 31, Eduard Shishkin (developer and maintainer of ReiserFS 4) would announce a new version, one of the fastest file systems for Linux — ReiserFS 5..
The fifth version introduces a new method for combining block devices into logical volumes.
I believe this represents a qualitatively new level in the development of file systems (and operating systems) — local volumes with parallel scalability.
Reiser5 does not implement its own block layer like ZFS, but is carried out using the file system's means. The new data distribution algorithm 'Fiber-Striping' will allow for more efficient composition of a logical volume from devices of different sizes and bandwidths, unlike the traditional combination of file systems and RAID/LVM.
This and other features of the new Reiser5 version should provide it with a higher level of performance compared to Reiser4.
The patch for Linux kernel 5.4.6 can be found at SourceForge.
The updated utility Reiser4Progs with initial support for Reiser 5 is also available there.
