Micron's HSE Open-Source Storage Engine Ticks Up To v1.7.1

Announced at the end of April was Micron's HSE as a new open-source storage engine designed for offering speedy performance and lower latency on modern solid-based storage, especially for systems employing 3D XPoint technology. Version 1.7.1 of HSE was released today as their first open-source release since going public with this technology.

Reiser5 File-System Working On New Features Like Data Tiering, Burst Buffers

Reiser5 was announced back on New Year's Eve with support for local volumes and supporting parallel scaling out and other improvements over the long-in-development but never mainlined Reiser4. While Reiser5 was not met with enthusiasm, Edward Shishkin has continued working on this next-generation file-system and today announced the latest round of improvements.

Linux 5.8 To See Faster FUSE Write Performance

FUSE for file-systems in user-space while being criticized by developers in the past and known for being slower than kernel native file-systems is seeing another write optimization come Linux 5.8.

Linux Kernel Seeing Workaround Revived For Buggy Micron NAND Block Erase Behavior

A new patch series has been revived from work originally published by Micron back in 2018 for dealing with the behavior on their planar 2D NAND devices where in rare cases when issuing block erase commands, the flash block might not actually be erased and this could lead to further problems down the road when touching said block.

Zstd Compression Under Review For OpenZFS

The ZFS file-system has long offered transparent file-system compression via the likes of LZ4 and Gzip and while now Zstd compression is under review for OpenZFS and seeking testing from the community.

Linux 5.8's Multi-Queue Block Code Plumbed To Support Inline Encryption

For a number of months now various Google engineers have been working on inline encryption support for FSCRYPT in order to offer better encryption performance on modern SoCs. That FSCRYPT side work is coming together and now also queued up for Linux 5.8 is plumbing inline encryption into blk-mq.

FSCRYPT Inline Encryption Still Being Prepared For The Linux Kernel

For a number of months now Google engineers have been working on FSCRYPT inline encryption capabilities for EXT4 and F2FS. The work is designed to offer better encryption performance on modern SoCs by having the encryption/decryption happen within the block layer as part of the bio and in turn leveraging the inline encryption hardware on modern Arm SoCs. The work still isn't merged but looks like it could be getting closer.

Btrfs Authenticated File-System Support Looks To Be Revived

Last year a SUSE developer sent out a set of patches adding authentication support to the Btrfs file-system. Btrfs already has checksums on meta-data blocks and data blocks while the original implementation of these authentication patches was performing HMAC on a SHA256 checksum as a keyed hash. A proper key in turn is then needed to mount a verified file-system.

Samsung Respins exFAT-Utils As exFATprogs In New Release

A few weeks ago the Samsung engineers responsible for the new Microsoft exFAT Linux kernel driver released exFAT-Utils as their user-space utilities for managing and creating exFAT file-systems under Linux. A new release is out and exFAT-Utils has been re-spun as exfatprogs.

OpenZFS Merges The New FreeBSD Support

FreeBSD developers have been working on transitioning to using OpenZFS as their ZFS file-system upstream code rather than the dormant Illumos base. That initial FreeBSD support has been mainlined this week into the OpenZFS repository, now providing a common code-base between for the open-source ZFS file-system code between Illumos, FreeBSD, Linux, and work-in-progress macOS.

F2FS Added Zstd Compression With Linux 5.7 While Now is Working On LZO-RLE

With Linux 5.6 the flash-focused F2FS file-system added LZO and LZ4 compression support for enhancing performance and ideally extending flash storage life by reducing the amount of writes. Added meanwhile for the current Linux 5.7 cycle was F2FS Zstd compression support. Now looking ahead to Linux 5.8, it looks like LZO-RLE support is being baked.

XFS Has A Second Round Of Improvements For Linux 5.7

Last week the XFS file-system saw its first round of updates for the Linux 5.7 kernel cycle that included preparations for supporting online repair in the future as well as many underlying code improvements. A second round of code improvements were sent in on Thursday for this mature file-system.
