'winbind use default domain' doesn't appear to work with ntlm_auth
Hi everyone,
We just upgraded Samba from 4.4.5 to 4.6.5 and appear to be experiencing a problem with authentication, when the RPC domain is not supplied as part of the username.
I have two scenarios where this has cropped up:
RADIUS authentication using ntlm_auth
Apache HTTP using mod_auth_ntlm_winbind
RADIUS authentication:
We use the freeRADIUS 'mschap' module to provide

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?

btrfs problems and fedora 14
I thought I would try btrfs on a new installation of f14. yes, I know
its experimental but stable so it seemed to be a good time to try it.
I am not sure if I have missed something out of all my searching but am
I correct in thinking that currently:

obscure out of space, df and fi df are way off
Very low priority.
No user data at risk.
8GB virtual disk being installed to, and the installer is puking. I''m trying to figure out why.
I first get an rsync error 12, followed by the installer crashing. What''s interesting is this, deleting irrelevant source file systems, just showing the mounts for the installed system:

flush-btrfs-1 hangs when building openwrt
Hi,
Since update to 2.6.37 I can''t build openwrt on my btrfs buildroot anymore.
I''m not sure if this is related to the other flush-btrfs-1 thread.
plenty of diskspace is free:
/dev/mapper/cruor-build
97G 68G 27G 73% /opt/build
It always hangs when openwrt builds the ext4 image and runs tune2fs on it.

BUG while writing to USB btrfs filesystem
While untar''ing an image to an sd card via a reader, I got the
following bug. The system also has a btrfs root, and a whole swath of
processes went into uninterruptable sleep. I was able to poke around
via ssh and sysrq, and already had netconsole set up to capture the
bug.
Root fs is on /dev/sdi1, and /dev/sdj2 is the card reader which was
the target of the untar.

raw partition or LV for btrfs?
I notice this question on the wiki/faq:
https://btrfs.wiki.kernel.org/index.php/UseCases#What_is_best_practice_when_partitioning_a_device_that_holds_one_or_more_btr-filesystems
and as it hasn''t been answered, can anyone make any comments on the subject
Various things come to mind:
a) partition the disk, create an LVM partition, and create lots of small
LVs, format each as btrfs

BTRFS partition won't mount
Hello all,
I recently had a power failure and can no longer mount my /home directory. The harddrive has two BTRFS partitions: sda7(/) and sda8(/home). The / partition loads up just fine, but /home does not. I''ve tried btrfsck as shown below and I''ve included dmesg pertaining to btrfs. This is on ArchLinux and the software versions are as follows:

RHEL4 as 64-bit HVM guest -- not starting in 64 bit mode
I''m trying to install RHEL 4 on an HVM (Core 2 Duo). However, when
the RHEL installer tries to start the kernel, it complains that the
CPU doesn''t support extended mode, and that I should use a 32-bit

This can be done in two ways, one - using attr which is user land

tftp problems with VIA EPIA-M board
I'm trying to boot linux on a VIA EPIA-M board (a Nehemiah-based
M10000), and I'm having some trouble with it. I'm watching the network
transactions with ethereal, and I'm seeing a failure at what appears
to be the tftp stage.
The M10000 picks up its IP address from the dhcp server (ISC

[RFC] New attempt to a better "btrfs fi df"

Hash: SHA1
Hi all,
this is a new attempt to improve the output of the command "btrfs fi df".
The previous attempt received a good reception. However there was no a
general consensus about the wording.
Moreover I still didn''t understand how btrfs was using the disks.
A my first attempt was to develop a new command which shows how the

I''ve had a go at determining exactly what happens when you create a
