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

After upgrading from 2.6.39-rc7 to 2.6.39 this morning, I tried to mount my 3 disk btrfs volume (no subvolumes, space caching enabled, lzo compression) and received some parent transid errors (going back to rc7 didn''t help, though): btrfs: disk space caching is enabled parent transid verify failed on 6038227976192 wanted 337418 found 337853 parent transid verify failed on 6038227976192

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". Now I''m not able to mount my btrfs / and /home (both on the same partition) anymore: device fsid SOME-UUID devid 1 transid 84229 /dev/dm-0 parent transid verify failed on 77078528 wanted 83774 found 84226

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

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 # mount /dev/mapper/vg00-btrfsvol0_0 /mnt/btrfs0 mount: wrong fs type, bad option, bad superblock on /dev/mapper/vg00-btrfsvol0_0, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or

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:

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

I booted the guest in which i was testing btrfs (transient ENOSPC issues, etc). It booted in emergency mode.

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:

Hi, I have a home server on Linux Arch (kernel 3.11.2) that uses multi-device btrfs on root filesystem. Until recently it worked completely fine. And yesterday I rebooted it and the machine did not wake up. I booted from a USB (kernel 3.10) and tried to mount the filesystem. Here is OOPs I see [ 41.676217] device fsid 25e6a6fa-fe1f-4be5-a638-eeac948f8c21 devid 8 transid 164237 /dev/sda [

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

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).

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

Hi! The problem is that the BTRFS raid10 filesystem without any understandable cause refuses to mount. Here is dmesg output: [77847.845540] device label linux-btrfs-raid10 devid 3 transid 45639 /dev/sdc1 [77848.633912] btrfs: allowing degraded mounts [77848.633917] btrfs: enabling auto defrag [77848.633919] btrfs: use lzo compression [77848.633922] btrfs: turning on flush-on-commit [77848.658879]

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