btrfsprogs: cases of snapshot failures
Since btrfs does not do recursive atomic snapshots (which I am ok with),
I am doing this myself. A handful of suggestions/problems came up.
1. Maybe btrfsprogs could gain an option to do recursive non-atomic
snapshots at the userspace level, simply invoking low-level atomic
snapshots one by one?
For the following, the kernel is 3.4.4 with the too-overloaded "0.19"

minimum kernel version for btrfsprogs.0.20?
Creating a btrfs file system using btrfs-progs-0.20.rc1.20130308git704a08c-1.fc19, and either kernel 3.6.10-4.fc18 or 3.9.0-0.rc3.git0.3.fc19, makes a file system that cannot be mounted by kernel 3.6.10-4.fc18. It can be mounted by kernel 3.8.4. I haven''t tested any other 3.8, or any 3.7 kernels.
Is this expected?

New btrfs-progs integration branch
I''ve just pushed out a new integration branch to my git repo. This
is purely bugfix patches -- there are no new features in this issue of
the integration branch. I''ve got a stack of about a dozen more patches
with new features in them still to go. I''ll be working on those
tomorrow. As always, there''s minimal testing involved here, but it

wrong values in "df" and "btrfs filesystem df"
Hallo, linux-btrfs,
First I create an array of 2 disks with
mkfs.btrfs -d raid0 -m raid1 /dev/sdb1 /dev/sdd1
and mount it at /srv/MM.
Then I fill it with about 1,6 TByte.
And then I add /dev/sde1 via
btrfs device add /dev/sde1 /srv/MM
btrfs filesystem balance /srv/MM
(it run about 20 hours)
Then I work on it, copy some new files, delete some old files - all
works well. Only

btrfs-progs branch updated
Hi everyone,
I''ve updated the master branch with the pending stable btrfs-progs
commit that should make the 0.20 release.
Thanks to Hugh for helping to queue up a few of them. We''ll have more
frequent releases from here as we pull in the major new features going
into progs (raid5/6, send/receive, quotas, fsck improvements).
Please give it a shot and let me know if you see any

Horrible btrfs performance on cold cache
Hi,
I use btrfs on most of my volumes on my laptop, and I''ve always felt
booting was very slow, but definitely sure is slow, is starting up
Google Chrome:
encrypted ext4: ~20s

I have tried different things to find out exactly what is the issue,
but haven''t quite found it yet.

Possible to exclude an event in Puppet dashboard?
Hi All,
I was wondering if it is possible to NOT show an event in puppet dashboard.
I have an exec resource that fires of a ruby script. This is triggering a
changed event on every run, but actually I want to exclude this from
showing up as "CHANGED"
Is this possible, if so how can I achieve this?

site.pp referring to other manifests without modules
Hi all,
I want to do some code reuse, and modules seem overkill. Is it possible to
have something like this?
A file called myuser.pp
class myuser {
user {...}
file {...}
...
}
Then in site.pp have this:
node ''foo.example.com'' {
include myuser
.. other things ..
}
node ''bar.example.com'' {
include myuser
.. other things ..
}

[PATCH] Btrfs: use i_version instead of our own sequence
We''ve been keeping around the inode sequence number in hopes that somebody
would use it, but nobody uses it and people actually use i_version which
serves the same purpose, so use i_version where we used the incore inode''s
sequence number and that way the sequence is updated properly across the
board, and not just in file write. Thanks,

Remove certificate requests
Hi,
I''ve got some certificate requests on my puppet master that I wish to
remove. It looks like the "puppet cert" tool doesn''t have an option for
doing that? What''s the best approach, just manually remove them from the
puppet/ssl/ca/requests directory?

[RFC][PATCH 1/2] Btrfs: try to allocate new chunks with degenerated profile
If there is no free space, the free space allocator will try to get space from
the block group with the degenerated profile. For example, if there is no free
space in the RAID1 block groups, the allocator will try to allocate space from
the DUP block groups. And besides that, the space reservation has the similar
behaviour: if there is no enough space in the space cache to reserve, it will

Option LABEL
Hallo, linux-btrfs,
please delete the option "-L" (for labelling) in "mkfs.btrfs", in some
configurations it doesn''t work as expected.
My usual way:
mkfs.btrfs -d raid0 -m raid1 /dev/sdb /dev/sdc /dev/sdd ...
One call for some devices.
Wenn I add the option "-L mylabel" then each device gets the same label,
and therefore some other programs
