Btrfs-progs

Userspace utilities to manage btrfs filesystems. License: GPLv2.

Btrfs is a copy on write (COW) filesystem for Linux aimed at implementing advanced features while focusing on fault tolerance, repair and easy administration.

This repository hosts following utilities:

  • btrfs — the main administration tool (manual page)
  • mkfs.btrfs — utility to create the filesystem (manual page)

See INSTALL for build instructions.

Release cycle

The major version releases are time-based and follow the cycle of the linux kernel releases. The cycle usually takes 2 months. A minor version releases may happen in the meantime if there are queued bug fixes or minor useful improvements.

Development

The patch submissions, development or general discussions take place at linux-btrfs@vger.kernel.org mailinglist, subsciption not required.
