Reiser4 File-System Is Still Ticking In 2019 - Now Updated For Linux 5.3 Compatibility

Filed under
Linux
Reiser

Edward Shishkin continues near single-handedly maintaining the out-of-tree Reiser4 code that at this point still has no apparent trajectory towards mainline. The former Namesys developer previously indicated it's unlikely to see Reiser4 merged unless there is a company backing it to get it through the review process for merging into mainline. While Reiser4 was quite promising for its early time, it's only getting more difficult with Reiser4 effectively stagnating for years now while SUSE/openSUSE continues backing Btrfs, Ubuntu increasingly investing in ZFS support, Red Hat developing Stratis, XFS continuing to be advanced by Red Hat and others as well, Google continuing to invest in the likes of EXT4/F2FS, and there also being Bcachefs and other open-source storage solutions that are more promising than Reiser4 in 2019. Nevertheless, the out-of-tree kernel patches continue to be updated.

Reiser4 Brought To The Linux 5.0 Kernel

Filed under
Reiser

For those still using the out-of-tree Reiser4 file-system, it may be about time to consider alternatives like Btrfs, XFS, ZFS On Linux, F2FS, or even the likes of Stratis and Bcachefs. But should you still be using this once promising file-system, the out-of-tree patches have been revised to now work with the Linux 5.0 kernel.

There still is no trajectory for Reiser4 to the mainline Linux kernel with no major companies or other stakeholders backing Reiser4 but just a small group of developers and enthusiasts left working on this successor to ReiserFS. With the latest code posted on Friday by former Namesys developer Edward Shishkin, the Reiser4 kernel driver has been re-based to the Linux 5.0 kernel but with no other changes to the file-system noted.

Reiser4 File-System Benchmarks With Linux 4.17

Linux
Reiser

It's been about three years since last carrying out any file-system performance benchmarks of Reiser4, but being curious how it stacks up against the current state of today's mainline Linux file-systems, here are some fresh performance tests of Reiser4 using the Linux 4.17 kernel. The Reiser4 performance was compared to Reiserfs, EXT4, Btrfs, XFS, and F2FS.

Reiser4 Updated For Linux 4.14 & Introduces Zstd Compression Support

Filed under
Reiser

The out-of-tree Reiser4 file-system driver has been updated with compatibility for the latest Linux 4.14 stable series. Besides reworking the code to run on Linux 4.14, this controversial file-system has also added support for Zstd file-system compression.

Linux 4.14 introduced Zstd support in the mainline kernel and wired it in for SquashFS and Btrfs. Our Btrfs Zstd benchmarks have been promising for transparent file-system compression compared to the other supported algorithms. Reiser4 has now picked up Zstd compression as an eventual replacement to their Gzip compression support.

Reiser4 Is Now Ready For Linux 4.13

Filed under
Reiser

For those wanting to use the Reiser4 file-system with the just-released Linux 4.13 kernel, patches are already available.

Less than one week after the release of the Linux 4.13 stable kernel, Edward Shishkin has already released an updated patch for the out-of-tree Reiser4 file-system for working with this new stable series.

Reiser4 Updated For Linux 4.12, Experimental Data Striping Support

Filed under
Reiser

Those using the Reiser4 file-system in some capacity can now safely upgrade to the Linux 4.12 kernel.

Edward Shishkin has updated this out-of-tree file-system for the Linux 4.12 kernel so it can be built with the latest mainline stable release.

Reiser4 Updated For The Linux 4.10 Kernel

Filed under
Reiser

The out-of-tree Reiser4 file-system has been updated for the Linux 4.10 kernel.

Reiser4 for the Linux 4.10.0 kernel is available as of earlier this week, managing to release their updated file-system driver code quite promptly. This port to Linux 4.10 yielded a few changes to the Reiser4 code as they re-based to this Linux kernel with the ->readlink() of inode operations being removed as well as the WRITE_FLUSH_FUA flag being removed.

Reiser4 Is Now Available For Linux 4.9, Mirror Code Almost Stable

Filed under
Reiser

For those that haven't yet switched to Btrfs, ZFS On Linux, or running EXT4/XFS but holding out hope for Reiser4, this out-of-tree file-system code has been updated for Linux 4.9.

Reiser4 was released for Linux 4.9.0 last weekend but then a revised patch series came out three days ago to fix some problems with this port to 4.9. With the new Reiser4 patches built against Linux 4.9.1, all should be well if you want to use this experimental file-system on the newest Linux kernel.

Reiser4 Now Available For Linux 4.8 Kernel

Filed under
Reiser

While Linux 4.9 will be released in just a few weeks, the remaining Reiser4 file-system developers have just updated their code to support the Linux 4.8 stable kernel.

Reiser4 for Linux 4.8.0 is now available for those wanting to run this out-of-tree file-system on the current stable kernel. The Reiser4 kernel is now compatible with 4.8 and there is also a kernel oops fix when mounting forward-incompatible volumes, unneeded assertions were removed, some VFS changes were made, and there is now rename2 support.

Reiser4 Implements Mirror & Failover Support

Filed under
Reiser

Edward Shishkin, one of the last remaining Reiser4 developers and the one who has been leading this out-of-tree file-system the past few years, has implemented logical volumes support with support for mirrors (in effect, RAID 0) and failover support at the file-system level.

Shishkin quietly announced on Sunday, "Reiser4 will support logical (compound) volumes. For now we have implemented the simplest ones - mirrors. As a supplement to existing checksums it will provide a failover - an important feature, which will reduce number of cases when your volume needs to be repaired by fsck."

Meet The New Linux Desktop That Offers A Unique Twist On Ubuntu 19.10

Are you a fan of the Cinnamon Desktop used in Linux Mint, but prefer more recent software and the familiarity of the Ubuntu ecosystem? If so, there’s a brand new spin of Ubuntu 19.10 that may interest you. Say hello to Ubuntu Cinnamon (or, as Michael Tunnell from This Week in Linux cleverly dubbed it, “CinnaBuntu”). Ubuntu Cinnamon is a brand new “remix” project that incorporates the Cinnamon Desktop Environment into Ubuntu. It’s not an official “flavor” of Ubuntu, but the developers are hoping that — like Ubuntu Budgie and Ubuntu MATE before it — it’s welcomed by both the community and Canonical to eventually join the ranks of the official Ubuntu family.

Google Releases Chrome 79 for Linux, Windows, and Mac with 51 Security Fixes

Chrome 79 has been in development since earlier this fall and entered beta testing at the end of October, when Google gave us a glimpse of the new features and improvements to come. And now, users can now enjoy all of them if they update their Chrome web browser to version 79.0.3945.79, which is rolling out now to Linux, Windows, and Mac desktop platforms. With Chrome 79, Google brings VR (Virtual Reality) support to the Web with a new API called WebXR Device API, which allows developers to create immersive experiences for smartphones, as well as head-mounted displays. This also paves the way for the development of many other similar emerging technologies, among which we can mention AR (Augmented Reality). Read more Direct:Stable Channel Update for Desktop

The latest Linux kernel is headed to Chromebooks in the very near future and that’s a big deal

For those of you who may not be familiar with the subject, Google’s Chrome OS that powers millions of Chromebooks is built on the Linux kernel. I’ll save you the long-winded explanation of what the Linux kernel is and how it works for two reasons. One, it would take all day. Two, I’m not a developer and I would likely confuse myself and you in the process. Apart from numerous Linux distributions and Chrome OS, the Linux kernel is at the heart of the Android operating system as well as various embedded devices and products such as smart TVs and webcams.
