Arne Jansen 6d37fbfc1f Btrfs-progs: tool to visualize fragmentation
This tool draws per-chunk pngs representing the allocation map. A black
or colored dot means the block is allocated.
The output is written to a subdirectory, together with an index.html to be
viewed in a browser.
There are options to control whether color should be used and which block
group types should be printed.
To build, you need to have libpng and libgd installed. It is not part of
the 'all' target, so please build it explicitely with make btrfs-fragments.

A (rather untypical) example can be seen at

http://sensille.com/fragments

Please regard this as a first scratch version and feel free to improve it :)

Goffredo Baroncelli f243fcd1b2 Removing btrfsctl, btrfs-vol, btrfs-show
With the commit 002d021c (committed October 2011)
btrfsctl, btrfs-vol, btrfs-show were declared deprecated.
The last patches related to these commands are dated December 2010.

These tools are replaced by the "btrfs" tool in all the
functionality.

This commit removes all the related code.

David Sterba 5e24225670 btrfs-progs: don't link binaries to a dynamic library
Linking 'btrfs' and other binaries against the dynamic library makes it
tedious to use directly from the git repo. This is useful for testing
various fixes, but now it'd need to also set LD_LIBRARY_PATH or install
the library to a known path.

Add a target for static library and use it for linking, the dynamic

Mark Fasheh e5cb128a95 btrfs-progs: libify some parts of btrfs-progs
External software wanting to use the functionality provided by the btrfs
send ioctl has a hard time doing so without replicating tons of work. Of
particular interest are functions like btrfs_read_and_process_send_stream()
and subvol_uuid_search(). As that functionality requires a bit more than
just send-stream.c and send-utils.c we have to pull in some other parts of
the progs package.

This patch adds code to the Makefile and headers to create a library,
libbtrfs which the btrfs command now links to.

Eric Sandeen 2a2d8e1962 btrfs-progs: require mkfs -f force option to overwrite filesystem or partition table
The core of this is shamelessly stolen from xfsprogs.

Use blkid to detect an existing filesystem or partition
table on any of the target devices.  If something is found,
require the '-f' option to overwrite it, hopefully avoiding
disaster due to mistyped devicenames, etc.

# mkfs.btrfs /dev/sda1

WARNING! - Btrfs v0.20-rc1-59-gd00279c-dirty IS EXPERIMENTAL
WARNING! - see http://btrfs.wiki.kernel.org before using

/dev/sda1 appears to contain an existing filesystem (xfs).
Use the -f option to force overwrite.

David Woodhouse 4d48b96b28 Add basic RAID[56] support
David Woodhouse originally contributed this code, and Chris Mason
changed it around to reflect the current design goals for raid56.

The original code expected all metadata and data writes to be full
stripes.  This meant metadata block size == stripe size, and had a few
other restrictions.

This version allows metadata blocks smaller than the stripe size.  It
implements both raid5 and raid6, although it does not have code to
rebuild from parity if one of the drives is missing or incorrect.

Josef Bacik 124053b1d9 Btrfs-progs: detect if the disk we are formatting is a ssd
Patch rebased because of changes in mkfs.c but otherwise the same
as created by Josef Bacik

SSD's do not gain anything by having metadata DUP turned on.  The underlying
file system that is a part of all SSD's could easily map duplicate metadat
blocks into the same erase block which effectively eliminates the benefit of
duplicating the metadata on disk.  So detect if we are formatting a single
SSD drive and if we are do not use DUP.  Thanks,

This completely replaces the existing subcommand infrastructure, which
is not flexible enough to accomodate our needs.  Instead of a global
command table we now have per-level tables and command group handlers,
which allows command-group-specific handling of options and subcommands.
The new parser exports a clear interface and gets out of the way - all
control over how matching is done is passed to commands and command
group handlers.

One side effect of this is that command implementors have to check the
number of arguments themselves - patch to fix up all existing commands

Goffredo Baroncelli e8f47cf068 Add the "btrfs filesystem label" command
Hi all,

this patch adds the command "btrfs filesystem label" to change (or show) the
label of a filesystem.
This patch is a subset of the one written previously by Morey Roof. I
included the user space part only. So it is possible only to change/show a
label of a *single device* and *unounted* filesystem.

The reason of excluding the kernel space part, is to simplify the patch in
order to speed the check and then the merging of the patch itself. In fact I
have to point out that in the past there was almost three attempts to propose
this patch, without success neither complaints.

Chris, let me know how you want to proceed. I know that you are very busy,
and you prefer to work to stabilize btrfs instead adding new feature. But I
think that changing a label is a *essential* feature for a filesystem
managing tool. Think about a mount by LABEL.

To show a label

$ btrfs filesystem label <device>

To set a label

$ btrfs filesystem label <device> <newlabel>

Please guys, give a look to the source.
Comments are welcome.

You can pull the source from the branch "label" of the repository
