Hi All, the following patches implement the recursively snapshotting and deleting of a subvolume. To snapshot recursively you must pass the -R switch: # btrfs subvolume create sub1 Create subvolume ''./sub1'' # btrfs subvolume create sub1/sub2 Create subvolume ''sub1/sub2'' # btrfs subvolume snapshot -R sub1 sub1-snap Create a snapshot of

This is the next patch series for scrub userland tools. Change log v1->v2: - commands now reachable as "btrfs scrub ..." instead of "btrfs filesystem scrub ..." - ability to scrub a single device instead of a whole file system - superfluous command line options removed - resume is now a separate command ("scrub resume") instead of "scrub start -r" -

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

This is a first draft of a subvolume quota implementation. It is possible to limit subvolumes and any group of subvolumes and also to track the amount of space that will get freed when deleting snapshots. The current version is functionally incomplete, with the main missing feature being the initial scan and rescan of an existing filesystem. I put some effort into writing an introduction into

Most fixes are trivial. The one from Alex is fixing a real bug that several users have reported. Alex sent the patch half a year ago and it was not yet integrated. The patch "Use /proc/mounts instead of /etc/mtab" is a repost. The patch "btrfs-receive optionally honors the end-cmd" is a preparation step to allow backup tools to multiplex a single communication stream (e.g. a
