Austin S. Hemmelgarn fe520b5cdc btrfs-progs: add option to run balance as daemon 
Currently, balance operations are run synchronously in the foreground.
This is nice for interactive management, but is kind of crappy when you
start looking at automation and similar things.

This patch adds an option to `btrfs balance start` to tell it to
daemonize prior to running the balance operation, thus allowing us to
preform balances asynchronously.  The two biggest use cases I have for
this are starting a balance on a remote server without establishing a
full shell session, and being able to background the balance in a
recovery shell (which usually has no job control) so I can still get
progress information.

Because it simply daemonizes prior to calling the balance ioctl, this
doesn't actually need any kernel support.

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.
