OpenZFS 2.4.4 Adds Linux Kernel 7.2 Support, New MMP Recovery Tool

OpenZFS 2.4.4 is out with Linux 7.2 compatibility, a new zhack mmp reclaim command, DDT fixes, and numerous reliability improvements.

Kent Overstreet says Bcachefs is no longer experimental, while broader production use still calls for careful judgment.

ZeroFS is a new open-source project that exposes S3-compatible storage over NFS, 9P, and NBD for Linux systems.

OpenZFS 2.4.3 is now available with storage fixes, improved Linux mount option handling, and compatibility with Linux kernels up to 7.0.

OpenZFS 2.4.2 brings Linux kernel 7.0 compatibility, plus fixes for dRAID, rebuilds, block cloning, snapshots, and mount handling.

Bcachefs 1.38 fixes mount stalls, improves discard handling, and speeds up snapshot-heavy systems with journal and allocator changes.

Bcachefs 1.37 introduces stable erasure coding, improved crash recovery, enhanced subvolume tools, and support for Linux kernel 7.0.

OpenZFS 2.4.1 adds Linux 6.19 support, improves FreeBSD compatibility, and delivers dozens of stability and build fixes across platforms.

Linux kernel 7.0 could introduce real-time XFS filesystem health events, enabling a userspace daemon to detect and automatically repair issues.

A new Linux proposal introduces DAXFS, a read-only filesystem that bypasses page cache for direct access to shared memory.
