I received a report from the release engineering side of the house that xfs_scrub without the -n flag (aka fix it mode) would try to fix a broken filesystem even on a kernel that doesn't have online repair built into it: # xfs_scrub -dTvn /mnt/test EXPERIMENTAL xfs_scrub program in use! Use at your own risk! Phase 1: Find filesystem geometry. /mnt/test: using 1 threads to scrub. Phase 1: Memory used: 132k/0k (108k/25k), time: 0.00/ 0.00/ 0.00s <snip> Phase 4: Repair filesystem. <snip> Info: /mnt/test/some/victimdir directory entries: Attempting repair. (repair.c line 351) Corruption: /mnt/test/some/victimdir directory entries: Repair unsuccessful; offline repair required. (repair.c line 204) Source: https://blogs.oracle.com/linux/post/xfs-online-filesystem-repair It is strange that xfs_scrub doesn't refuse to run, because the kernel is supposed to return EOPNOTSUPP if we actually needed to run a repair, and xfs_io's repair subcommand will perror that. And yet: # xfs_io -x -c 'repair probe' /mnt/test # The first problem is commit |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
