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

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

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

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''m running OpenSuse 12.2 with kernel 3.5.3 HBA= LSI 1068e using the MPTSAS driver (patched) (https://patchwork.kernel.org/patch/1379181/) SANOS1:/media # uname -a Linux SANOS1 3.5.3 #3 SMP Sun Sep 2 18:44:37 CEST 2012 x86_64 x86_64 x86_64 GNU/Linux I''ve tried to simulate a disk replacement but it seems that now /dev/sdg is stuck in the btrfs pool (RAID10) SANOS1:/media #

fs_info->last_trans_log_full_commit is a 64bits variant, we might get a wrong value on the 32bit machines if we access it directly. Fix it by atomic operation.

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''ve been working to try to improve the write-ahead log''s performance, and I found that the bottleneck addresses in the checksum items, especially when we want to make a random write on a large file, e.g a 4G file. Then a idea for this suggested by Chris is to use sub transaction ids and just to log the part of inode that had changed since either the last log commit or the last

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

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! 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]

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, 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

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

Hi everyone, This patchset is the latest approach I''m using for the Ceph storage daemon to keep track of which data has safely committed to disk. The basic idea is to not use the (problematic) user transaction ioctls at all. Instead, the daemon quiesces its own write requests, initiates an async snapshot, and then continues. The snapshot approach is nice because it provides rollback.

Hi, I reported a bug to anaconda (rhbz 901905), but it might be btfs related.

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. Then btrfs device add /dev/sdj1 /mnt/btr results in # show Label: none uuid: 6bd7d4df-e133-47d1-9b19-3c7565428770 Total devices 4 FS bytes
