[PATCH v2 0/3] btrfs-progs: prevent mkfs from aborting with small volume
Here are 3 patches to avoid undesired aborts of mkfs.btrfs.
These are based on top of Chris''s btrfs-progs.git:

[PATCH 00/21] [RFC] Btrfs: restriper
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.

[PATCH v3 0/3] btrfs: quasi-round-robin for chunk allocation
In a multi device setup, the chunk allocator currently always allocates
chunks on the devices in the same order. This leads to a very uneven
distribution, especially with RAID1 or RAID10 and an uneven number of
devices.
This patch always sorts the devices before allocating, and allocates the
stripes on the devices with the most available space, as long as there
is enough space available. In a low

[PATCH][BTRFS-PROGS][V3] btrfs filesystem df
Hi Chris,
this serie of patches updated the command "btrfs filesystem
df". I update this command because it is not so easy to get
the information about the disk usage from the command "fi df" and "fi show".
This patch was the result of some discussions on the btrfs
mailing list. Many thanks to all the contributors.
From the man page (see 2nd patch):

[PATCH] fix enospc when there is plenty of space
...h Metadata writes, and happens _very_ infrequently. What has to
happen is we have to allocate have allocated out of the first logical byte on
the disk, which would set last_alloc to first_logical_byte(root, 0), so
search_start == orig_search_start. We then need to allocate for normal
metadata, so BTRFS_BLOCK_GROUP_METADATA | BTRFS_BLOCK_GROUP_DUP. We will do a
block lookup for the given search_start, block_group_bits() won''t match and
we''ll go to choose another block group. However because search_start matches
orig_search_start we go to see if we can allocate a chunk. If we are in the
situation t...

Hello,
This is the userspace part of restriper, rebased onto the new progs
infrastructure. Restriper commands are located under ''balance'' prefix,
which is now the top level command group. However to not confuse
existing users ''balance'' prefix is also available under ''filesystem'':

[PATCH 0 of 3 v2] PV-GRUB: add support for ext4 and btrfs
Hi,
The following patches add support for ext4 and btrfs to
PV-GRUB. These patches are taken nearly verbatim from those provided
by Fedora and Gentoo.
We''ve been using these patches for the PV-GRUB images available in EC2
for some time now with no problems.
Changes from v1:
- Makefile has been changed to check the exit code from patch
- The btrfs patch has been rebased to apply
