ZFS on Linux: Unlocking Advanced File System and Volume Management
Posted: 2024-02-15 17:00:00 Source: https://www.linuxjournal.com/content/zfs-linux-unlocking-advanced-file-system-and-volume-management
Introduction
In the realm of modern data management, few technologies hold as much promise and versatility as the ZFS file system. Originally developed by Sun Microsystems for their Solaris operating system, ZFS has gained widespread acclaim for its advanced features, robustness, and data integrity mechanisms. While ZFS was initially exclusive to Solaris and other Unix-like operating systems, its integration with Linux has opened up a world of possibilities for system administrators and enthusiasts alike.
This article delves into the intricate workings of ZFS on Linux, exploring its advanced file system and volume management capabilities. Whether you're a seasoned sysadmin looking to optimize your storage infrastructure or an adventurous user seeking to harness the power of ZFS for personal projects, this guide will equip you with the knowledge needed to master ZFS on Linux.
Understanding ZFS
At its core, ZFS is a next-generation file system designed to address the shortcomings of traditional filesystems while introducing a plethora of innovative features. One of the defining characteristics of ZFS is its unique approach to storage management through the use of storage pools. Unlike traditional file systems that rely on individual partitions or volumes, ZFS aggregates multiple storage devices into a single pool, allowing for dynamic allocation and management of storage resources.
Within a ZFS pool, data is organized into datasets, which serve as logical containers for files and directories. Datasets can be hierarchically structured, enabling administrators to create a flexible and scalable storage environment tailored to their specific needs. This hierarchical organization facilitates efficient data management and simplifies tasks such as backup, replication, and data migration.
Advanced Features of ZFS
One of the most compelling features of ZFS is its unparalleled data integrity and protection mechanisms. ZFS employs checksums to detect and mitigate data corruption, ensuring that stored data remains intact and reliable even in the face of hardware failures or silent data corruption. Additionally, ZFS utilizes a copy-on-write transactional model, which guarantees atomicity and consistency when writing data to disk, thereby minimizing the risk of data corruption and ensuring data integrity.
Another notable feature of ZFS is its support for snapshots and clones, which enable users to capture point-in-time copies of datasets for backup, replication, or experimentation purposes. Snapshots provide a read-only view of the dataset at a specific moment in time, allowing users to revert to previous states or extract specific versions of files without impacting the original data. Clones, on the other hand, allow users to create writable copies of snapshots, enabling rapid provisioning of new environments or testing scenarios.

Asahi Linux Project's OpenGL Support On Apple Silicon Officially Surpasses Apple's
Posted: 2024-02-15 07:00:00 Source: https://linux.slashdot.org/story/24/02/15/021216/asahi-linux-projects-opengl-support-on-apple-silicon-officially-surpasses-apples?utm_source=atom1.0mainlinkanon&utm_medium=feed
Andrew Cunningham reports via Ars Technica: For around three years now, the team of independent developers behind the Asahi Linux project has worked to support Linux on Apple Silicon Macs, despite Apple's total lack of involvement. Over the years, the project has gone from a "highly unstable experiment" to a "surprisingly functional and usable desktop operating system." Even Linus Torvalds has used it to run Linux on Apple's hardware. The team has been steadily improving its open source, standards-conformant GPU driver for the M1 and M2 since releasing them in December 2022, and today, the team crossed an important symbolic milestone: The Asahi driver's support for the OpenGL and OpenGL ES graphics have officially passed what Apple offers in macOS. The team's latest graphics driver fully conforms with OpenGL version 4.6 and OpenGL ES version 3.2, the most recent version of either API. Apple's support in macOS tops out at OpenGL 4.1, announced in July 2010. Developer Alyssa Rosenzweig wrote a detailed blog post that announced the new driver, which had to pass "over 100,000 tests" to be deemed officially conformant. The team achieved this milestone despite the fact that Apple's GPUs don't support some features that would have made implementing these APIs more straightforward. "Regrettably, the M1 doesn't map well to any graphics standard newer than OpenGL ES 3.1," writes Rosenzweig. "While Vulkan makes some of these features optional, the missing features are required to layer DirectX and OpenGL on top. No existing solution on M1 gets past the OpenGL 4.1 feature set... Without hardware support, new features need new tricks. Geometry shaders, tessellation, and transform feedback become compute shaders. Cull distance becomes a transformed interpolated value. Clip control becomes a vertex shader epilogue. The list goes on." Now that the Asahi GPU driver supports the latest OpenGL and OpenGL ES standards -- released in 2017 and 2015, respectively -- the work turns to supporting the low-overhead Vulkan API on Apple's hardware. Vulkan support in macOS is limited to translation layers like MoltenVK, which translates Vulkan API calls to Metal ones that the hardware and OS can understand. [...] Rosenzweig's blog post didn't give any specific updates on Vulkan except to say that the team was "well on the road" to supporting it. In addition to supporting native Linux apps, supporting more graphics APIs in Asahi will allow the operating system to take better advantage of software like Valve's Proton, which already has a few games written for x86-based Windows PCs running on Arm-based Apple hardware.
