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:

Unable to mount btrfs partition
Hello!
Today I downgraded from Ubuntu''s APT repo "oneiric-proposed" (which
brings some kernel 3.0.0-13) back to the standard repo "oneiric".
Now I''m not able to mount my btrfs / and /home (both on the same
partition) anymore:

fail to mount after first reboot
I created a 1TB RAID1. So far it is just for testing, no important data
on there.
After a reboot, I tried to mount it again

Damaged super block / fs root
I have accidently damaged the first block(s) of a btrfs partition
and can''t mount it anymore.
I can see that my data is still intact by running a command like:
cat /dev/sda5 | hexdump -C | more
Do any (experimental) tools exist which would allow me to recover the files?
Thank you

Recovering "parent transid verify failed"
Hey,
I''d start by saying that I know Btrfs is a still experimental, and so
there''s no guarantee that one would be able to help me at all... But I
thought I''ll try anyway :-)
Few months ago I bought a new laptop and installed ArchLinux on it,
with Btrfs on the root filesystem... I know, it''s not the smartest
thing to do...
After a few month I had issues with my

Question: How can I recover this partition? (unable to find logical $hugenum len 4096)
Hi list! I recently butchered my filesystem, and I was wondering if anyone knows how to help.
Problem: My filesystem is screwed up, and I can''t mount it at all right now. In the logs, the problem begins around 45s.
Background: I''m running a 6x4TB RAID5 array using md. I have a few virtual machines using said array, and one of them is a btrfs storage server. I ran into some

Is it possible to reclaim block groups once they are allocated to data or metadata?
Hello list,
recently reformatted my home partition from XFS to RAID1 btrfs. I used
the default options to mkfs.btrfs except for enabling raid1 for data
as well as metadata. Filesystem is made up of two 1TB drives.

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

The state of btrfs RAID6 as of kernel 3.13-rc1
Hi
What is the general state of btrfs RAID6 as of kernel 3.13-rc1 and the
latest btrfs tools?
More specifically:
- Is it able to correct errors during scrubs?
- Is it able to transparently handle disk failures without downtime?
- Is it possible to convert btrfs RAID10 to RAID6 without recreating the fs?
- Is it possible to add/remove drives to a RAID6 array?
Regards,
Hans-Kristian

Hi Everyone,
I am very new to this mailing list and very much interested in getting
into the internals of BTRFS file system
I was looking for mkfs.btrfs source code so that I can start getting
how the disk is formatted with btrfs system.
Can anyone of you redirect me to that place to download the btrfsprogs

Btrfs questions
i am looking at using btrfs for a new project and i have a few questions:
* i have heard that as it currently stands Btrfs has some issues to be used as a Lustre file system; is he aware of the issues and any plans to address these and integrate Btrfs in to Lustre
* any plans to support native clustering on Btrfs
* on ZFS the ZIL is a separate device, any plans to implement a the

How does btrfs behave on checksum mismatch?
I came across the tidbit that ZFS has a contract guarantee that the
data read back will either be correct (the checksum computed over the
data read from the disk matches the checksum stored on disk), or you
get an I/O error. Obviously, this greatly reduces the probability that
the data is invalid. (Particularly when taken in combination with the
disk firmware''s own ECC and checksumming.)
