Is anyone interested in some part of this filesystem to figure out how it failed? Or can I erase and start again?

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

Hi folks! Been using btrfs for quite a while now, worked great until now. Got power-loss on my machine and now i have the "parent transid verify failed on X wanted X found X" problem. So I can''t get it to mount. My btrfs is spread over sda (2tb), sdc(2tb), sdd(1tb). Is this something that an offline fsck could fix ? If so is the fsck-util being developed ? Is there a way to

Hello, trying out btrfs on my linux installation. I am running Funtoo with Linux 3.0 kernel. After a reboot kernel panicked (no access to error log since it is my root volume that failed). I get this using a rescue cd (2.6.38, btrfs v 0.19) and then trying to mount : [  752.129118] btrfs bad tree block start 0 131072 [  752.129152] btrfs: failed to read chunk root on sda5 [  752.132190] btrfs:

Hi there, after my filesystem is broken (I have no idea why, because last shut down was nomal) I tried to repair it with btrfsck ( Btrfs v0.20-rc1-56-g6cd836d). But unfortunately the process breaks with: parent transid verify failed on 29896704 wanted 392661 found 395689 parent transid verify failed on 29896704 wanted 392661 found 395689 parent transid verify failed on 29896704 wanted 392661

Hi, I''m having a filesystem that''s been a bit mangled by external causes, so I thought I''d see how much I could salvage (it''s not critical, though). Thus, I pulled btrfsck from git and ran: pannekake:~/btrfs-progs# ./btrfsck --repair /dev/mapper/pannekake-backup-btrfs It spit out a ton of warnings like these (I can get the whole log if you''re

So I''m having a bit of trouble with one of my btrfs filesystems. It isn''t mounting after a power failure. I can''t get restore or btrfsck to run, even on backup supers. I''ve pasted some output below. My btrfs-progs below come from git this morning, running on linux 3.2.0. # mount /dev/md2 /media/test/ mount: wrong fs type, bad option, bad superblock on

Hi devs, I can''t mount my btrfs-based external disk. I don''t know what happened to the disk, but usually it gets disconnected (usb cable pulled out) buy my 8 months old daughter.

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".

I created a 1TB RAID1. So far it is just for testing, no important data on there.

Hello I think, I somewhat destroyed my btrfs filesystem on my Ubuntu 13.04 kernel 3.8.0-25-lowlatency system. It got destroyed, because the system was hanging for some other reason and I had to remove power... When I try to mount my filesystem (there''s only one, with a few subfilesystems), the system crashes. Also btrfsck dies; always like this: a@ask-home:~$ sudo

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

I have a corrupted multi-device file system that got corrupted ages ago (as I recall, one of the drives stopped responding, causing btrfs to panic). I am hoping to recover some of the data. For what it''s worth, here is the dmesg output from trying to mount the file system on a 3.0 kernel: device label Media devid 6 transid 816153 /dev/sdq device label Media devid 7 transid 816153

Hello, I had a raid1 btrfs (540GB) on vanilla 3.6.3, a disk failed, and removed it at power off, plugged in a new one, partitioned it (to 110GB, by error), and added it to btrfs. I tried to remove the missing device, and it said "Input/output error" after a while. Next attempts simply gave "Invalid argument". I repartitioned, rebooted the system, and made the partition grow:
