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

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

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

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 again. Sorry for top posting. I have a 9 disk filesystem that does not mount anymore and need some help/advice so I can recover the data. What happened was that I was running a btrfs delete device under Ubuntu 13.04 Kernel 3.8 and after a long time of moving data around it crashed with a SEGV. Now the filesystem does not mount and none of the recovery options I have tried work. I have

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

Some programs like btrfsck should not be run on a mounted filesystem. This patch adds a check in btrfs_open_devices() for the mount status of every device belonging to the filesystem. The function check_mount() gets improved support for loopback devices. It now detects if the program is run on the file that is being used by the loopback device. Signed-off-by: Andi Drebes

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. Here''s the output from dmesg: [ 299.699543] parent transid verify failed on 528952573952 wanted 22726 found 22728 [ 299.700947] btrfs read error corrected: ino 1 off 528952573952 (dev

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, I have setup a RAID1 using 3 devices (500G each) on separate disks. After removing one disk physically the filesystem cannot be mounted in degraded nor in recovery mode. When putting the disk back in the filesystem can be mounted without errors. I did a cold-swap (powercycle after removal/insertion of the disk). Here are the details: - latest kernel 3.2.1 and btrfs-tools on xubuntu

My raid5 crashed, so i changed the old hdd and started the rebuild. But now i can''t mount the btrfs, the mount command frozen and the kernel give me in a loop the follwing lines: Jul 29 18:37:04 fileserver kernel: [ 1229.692268] verify_parent_transid: 2492 callbacks suppressed Jul 29 18:37:04 fileserver kernel: [ 1229.692274] parent transid verify failed on 6975016271872 wanted 204247

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. 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

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 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).

Hallo, linux-btrfs, I''ve (once again) tried "add" and "delete". First, with 3 devices (partitions): mkfs.btrfs -d raid0 -m raid1 /dev/sdk1 /dev/sdl1 /dev/sdm1 Mounted (to /mnt/btr), filled with about 100 GByte data.
