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

Filed under
Graphics/Benchmarks
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 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."

Reiser4 Now Has Support For The Linux 4.7 Kernel

Filed under
Reiser

The Reiser4 file-system now has support for the latest stable Linux kernel series, Linux 4.7.

Released this morning by Edward Shishkin was the updated Reiser4 file-system driver patch that provides compatibility for Linux 4.7.0. The only other change besides porting over to Linux 4.7 is a small returned optimization.

There's been no talk in a few years about attempting to mainline the Reiser4 file-system in the Linux kernel. Thus for now if you want to try out this once-promising file-system, swing by SourceForge to patch your kernel.

  • 6 Best Data Science and Machine Learning Courses for Beginners

    Many programmers are moving towards data science and machine learning hoping for better pay and career opportunities --- and there is a reason for it. The Data scientist has been ranked the number one job on Glassdoor for last a couple of years and the average salary of a data scientist is over** $120,000** in the United States according to Indeed. Data science is not only a rewarding career in terms of money but it also provides the opportunity for you to solve some of the world's most interesting problems. IMHO, that's the main motivation many good programmers are moving towards data science, machine learning and artificial intelligence.

  • Find the smallest number within a list with python

    In this example, we will create a python function which will take in a list of numbers and then return the smallest value. The solution to this problem is first to create a place holder for the first number within the list, then compares that number with other numbers within the same list in the loop. If the program found a number which is smaller than the one in the place holder, then the smaller number will be assigned to that place holder.

  • Basic Input, Output, and String Formatting in Python

    To be useful, a program usually needs to communicate with the outside world by obtaining input data from the user and displaying result data back to the user. This tutorial will introduce you to Python input and output. Input may come directly from the user via the keyboard, or from some external source like a file or database. Output can be displayed directly to the console or IDE, to the screen via a Graphical User Interface (GUI), or again to an external source.

  • Want to level up your Python? Join Weekly Python Exercise, starting July 2nd

    Let’s face it: Stack Overflow has made developers’ lives easier. Almost every time I have a question, I find that someone on Stack Overflow has asked it, and that people have answered it, often in great detail. I’m thus not against Stack Overflow, not by a long shot. But I have found that many Python developers visit there 10 or even 20 times a day, to find answers (and even code) that they can use to solve their problems.

  • Introducing pytest-elk-reporter

    Few years back I’ve wrote a post about how I’ve connected python based test to ELK setup - “ELK is fun”, it was using an xunit xml, parsing it and sending it via Logstash. Over time I’ve learn a lot about ElasticSearch and it’s friend Kibana, using them as a tool to handle logs. and also as a backend for a search component on my previous job. So now I know logstash isn’t needed for reporting test result, posting straight into elasticsearch is easier and gives you better control, ES is doing anything “automagiclly” anyhow nowadays.

  • OpenStack Stein feature highlights: vGPU support coming in Red Hat OpenStack Platform 15

    Red Hat is working on the next release of the supported enterprise distribution of OpenStack, Red Hat OpenStack Platform 15, based on the Stein community release. In this multi-part blog series, we’ll be examining some of the features that Red Hat and the open source community have collaborated on–starting with a look to future workloads, such as artificial intelligence. "How does OpenStack enable next generation workloads?" you ask. When it comes to computer-driven decision making, machine learning algorithms can provide adaptable services that can get better over time. Some of these workloads, such as facial recognition, require GPUs to ingest and process graphical data in real time. But the more powerful GPUs often used for machine learning and such are expensive, power-hungry, and can take up a lot of room in the servers' chassis. When working with GPUs at scale, optimized utilization is key to more cost effective machine learning.

  • Panfrost Gallium3D Picks Up Yet More Features Thanks To Collabora's Summer Internship

There's yet another batch of new features and improvements to talk about. Most of this feature work continues to be done by Panfrost lead developer Alyssa Rosenzweig who is interning at Collabora this summer and appears to be spending most of her time working on this reverse-engineered Arm graphics driver supporting their recent generations of IP.

  • Vulkan 1.1.112 Released While Open-Source ANV + RADV Drivers Continue Marching Along

    Vulkan 1.1.112 was outed this morning as the newest documentation update to this high performance graphics and compute API. Vulkan 1.1.112 is quite a mundane update with just documentation corrections and clarifications this go around and not any new extensions. But at least the clarifications should help out some and other maintenance items addressed by this Vulkan 1.1.112 release. It's not a surprise the release is so small considering Vulkan 1.1.111 was issued just two weeks ago.
