Read-Only Apple File-System Support Is Being Worked On For The Linux Kernel (APFS)

The past few years Apple has been developing APFS as the successor to the long-used HFS+ file-system. The Apple File-System is in use with macOS 10.13+ iOS 10.3, and their other platforms for offering a lot of features not found in HFS+ including much better performance. There is an open-source APFS kernel driver now under development for Linux in supporting this file-system.

ZFS On Linux Runs Into A Snag With Linux 5.0

While the Linux 5.0 kernel has a lot of enticing features and improvements, if you rely upon ZFS On Linux (ZOL) you will probably want to hold off on trying the Linux 5.0 release candidates at this time.

Another Attempt At Adding Encryption Support To Btrfs

While the Btrfs file-system supports many next-gen features from SSD optimizations to transparent file-system compression to snapshots, it hasn't natively offered any encryption support. There have been Btrfs encryption attempts in the past, but nothing that has panned out in mainline short of running Btrfs atop dm-crypt. A new patch series was published overnight having another go at adding AES encryption to Btrfs.

Reiser4 File-System Port To The Linux 4.20 Kernel

There hasn't been a formal Reiser4 file-system patch release since September when it was ported to the Linux 4.18 kernel, but via Git this week there is a port for the Linux 4.20 kernel should you want to utilize this once promising file-system under the latest stable patch series.

XFS RAID0 Benchmarks Across Twenty SSDs vs. EXT4 & Btrfs On Ubuntu Linux

Earlier this month were the FreeBSD ZFS vs. Linux EXT4/Btrfs RAID With Twenty SSDs. Besides interest in seeing ZOL tests (they're already planned upon the ZFS On Linux 0.8 release), there was also some interest by readers in seeing some XFS RAID tests side-by-side. Here are some of those XFS RAID benchmarks up against Btrfs and EXT4 from Ubuntu Linux.

Bcachefs Working Towards Online Fsck, Faster Mount Times

In the works now for over three years has been BCachefs that doesn't receive nearly as much attention as Btrfs, Stratis, ZFS On Linux, or other next-gen Linux storage options, but it does continue making progress and still possesses a lot of potential.

There Is Finally A User-Space Utility To Make EROFS Linux File-Systems

Back when Huawei introduced the EROFS Linux file-system earlier this year, there wasn't any open-source user-space utility for actually making EROFS file-systems. Even when EROFS was merged into the mainline tree, the user-space utility was still non-existent but now that issue has been rectified.
