similar to: Recovering "parent transid verify failed"

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

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. 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

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! 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, 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

After an unclean shutdown, my btrfs is now unmountable: device label root devid 1 transid 375202 /dev/sdc4 parent transid verify failed on 53984886784 wanted 375202 found 375201 parent transid verify failed on 53984886784 wanted 375202 found 375201 parent transid verify failed on 53984886784 wanted 375202 found 375201 btrfs: open_ctree failed btrfsck aborts: couldn''t open because of

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

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:

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 [

A few months ago, my btrfs storage array became corrupted because of a power failure. A while ago, I made this thread to try and resolve the problem. (http://www.digipedia.pl/usenet/thread/11904/15955/) You can find detailed information about the problem in the previous thread, but I am happy to provide any other details. It didn''t really go anywhere in the way of solving my problem. The

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
