Now with the below kernel patch, the excl operations like dev add/replace/resize and balance returns the btrfs error code defined in btrfs.h, this patch will help btrfs-progs (and thus user) to know the error string on the terminal (instead of /var/log/messages as previously kernel did). This patch depends on the btrfs kernel patch: btrfs: return btrfs error code for dev excl ops err

This series adds an initial implementation for scrub. It works quite straightforward. The usermode issues an ioctl for each device in the fs. For each device, it enumerates the allocated device chunks. For each chunk, the contained extents are enumerated and the data checksums fetched. The extents are read sequentially and the checksums verified. If an error occurs (checksum or EIO), a good copy

Hello, This patch series adds an initial implementation of restriper (it''s a clever name for relocation framework that allows to do selective profile changing and selective balancing with some goodies like pausing/resuming and reporting progress to the user. Profile changing is global (per-FS) so far, per-subvolume profiles require some discussion and can be implemented in future.
