XFS Could Gain a Self-Healing Feature in Linux Kernel 7.0
Linux kernel 7.0 could introduce real-time XFS filesystem health events, enabling a userspace daemon to detect and automatically repair issues.
The XFS filesystem could gain exciting new features, and more specifically, autonomous self-healing capabilities in the upcoming Linux kernel 7.0 cycle, following a pull request submitted by XFS maintainer Darrick J. Wong.
The proposal, called “xfs: autonomous self-healing of filesystems,” aims for the 7.0 merge window. It brings a new system to report filesystem problems in real time and lets userspace programs fix them automatically. This patchset uses new VFS error-reporting tools from Amutable’s CTO Christian Brauner, which are also planned for Linux kernel 7.0.
The main change adds a kernel feature that sends out health events when XFS finds problems like metadata corruption, file I/O errors, media check failures, or big changes such as shutdowns and unmounts.
