When writing to a newly created btrfs (vanilla 2.6.33-rc6, sparc64) the following messages are printed: [28617.650231] Kernel unaligned access at TPC[10101f18] btrfs_csum_final+0x38/0x60 [btrfs] [28617.745783] Kernel unaligned access at TPC[10101f18] btrfs_csum_final+0x38/0x60 [btrfs] [28654.589492] Kernel unaligned access at TPC[10101f18] btrfs_csum_final+0x38/0x60 [btrfs] [28654.685036] Kernel

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.

I converted an ext4 filesystem with btrfs-convert, mounted it, and wanted to do "lzop -d ...".

It doesn't appear to be using any kernel modules. I would have expected to see output such as this: supermin: internal insmod virtio.ko It seems as if you might not be setting SUPERMIN_MODULES; or maybe you

Hello Developers, it seems that i discovered a bug in btrfs while testing it on a zSeries mainframe :-) ## Test environment: - IBM System z900 Mainframe - Debian SID with 64 Bit Kernel - GIT Sources from git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-unstable.git - System runs as z/VM guest - 3 Virtual CPUs - 1 GB RAM Storage ## Initial Test Setup - Setup a Debian SID System with

Hi Konrad I encountered a bug when trying to bring offline a cpu then online it again in HVM. As I''m not very familiar with HVM stuffs I cannot come up with a quick fix. The HVM DomU is configured with 4 vcpus. After booting into command prompt, I do following operations. # echo 0 > /sys/devices/system/cpu/cpu3/online # echo 1 > /sys/devices/system/cpu/cpu3/online With

Now that we have SCTP offload capabilities in the kernel, we can add them to virtio as well. First step is SCTP checksum. We need a new freature in virtio to negotiate this support since SCTP is excluded with the stardard checksum and requires a little bit extra. This series proposes VIRTIO_NET_F_SCTP_CSUM feature bit. As the "little bit extra", the kernel uses a new bit in the skb

I ran into a panic while running find -xdev | xargs brtfs fi defrag ''{}''. I don''t remember the exact command because the history was not saved. I also started and stopped it a few times however. The kernel logs were on a different filesystem. Here is the kern.log:http://fpaste.org/9383/36729191/ My setup is two 2TB hard drives in raid 1. They are both sata drives so

Hi. Im writing a kernel module to extract some information from kernel, the module is working really fine in an AMD (AMD Athlon(tm) 64 X2 Dual Core Processor 3800+), but, when trying to run the module in a i7 (Intel(R) Core(TM) i7 CPU 930 @ 2.80GHz) Im facing some strange errors (see below). The kernel versions are just the same on both machines (2.6.34.10-0.2-xen #1 SMP x86_64 x86_64 x86_64

Simple tool to parse a fits-stream from stdout. Signed-off-by: Arne Jansen <sensille@gmx.net> --- The idea of the btrfs send stream format was to generate it in a way that it is easy to receive on different platforms. Thus the proposed name FITS, for Filesystem Incremental Backup Stream. We should also build the tools to receive the stream on different platforms. As a place to collect

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: btrfs-progs-unstable

This patch adds mixed back ref support for btrfs programs. The mixed back ref is a new disk format. back compatilibity is still not implemented.
