Hi all, This is the eleventh revision (+ more fixes suggested by Eric Sandeen) of a patchset that adds to XFS userland tools support for online metadata scrubbing and repair. Since v10 I've rebased to the latest for-next, fixed some wonky error messages, and fixed a few minor problems I found via code inspection. This patch series is more or less the same as a couple of weeks ago. We start by creating the basic shell of the program that can do argument parsing and error reporting, create some abstractions for the XFS ioctls that we use to iterate and scrub metadata, and then tie together all the in-kernel scrubbing in separate scrub phases. Next, we move on to checking the directory tree for connectivity and naming problems and add the infrastructure to perform an (optional) scan of the in-use parts of the disk media. We also implement a minimal preen -- if the fs checks out, we can try to run fstrim; and some basic progress reporting if the program is running interactively. Finally, we add some wrapper scripts to schedule scrubs of all the mounted filesystems; and the necessary systemd / cron infrastructure that is needed to automatically scan everything once a week. All of this is disabled by default. The systemd integration allows us to give scrub exactly the privileges it needs while walling off the rest of the system. If you're going to start using this mess, you probably ought to just pull from my git tree for xfsprogs[1]. This series relies on the libfrog patches sent earlier. Kernel support appeared in 4.15 and will become substantially more robust in 4.16. Comments and questions are, as always, welcome. --D [1] https://git.kernel.org/cgit/linux/kernel/git/djwong/xfsprogs-dev.git/log/?h=djwong-devel -- To unsubscribe from this list: send the line "unsubscribe linux-xfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
