Description Tim Jones 2014-01-28 21:49:34 UTC
Description of problem:
My btrfs filesystem has failed, after a reboot. No idea how to reproduce it - I'd not like to as I've just lost a lot of stuff! :(

I was seeing a lot of these kind of things:

[ 2095.846260] parent transid verify failed on 456197648384 wanted 142099 found 142097
[ 2095.846427] parent transid verify failed on 456197648384 wanted 142099 found 142097

I attempted to run 'btrfsck --repair' and 'btrfsck -b --repair' on the device, both core dumped (SEGV'd) part way through, and now I can't do anything else with the device.

Version-Release number of selected component:

Comment 11 Tim Jones 2014-01-28 22:00:37 UTC
I just found 'btrfs-zero-log' which has allowed me to re-mount the device ... attempting to update my backups now!

Comment 12 Tim Jones 2014-01-30 18:46:26 UTC
Unfortunately all the files had the correct file sizes, but they were also full of just a single 0x01 char, so all data was lost :(

Comment 13 Eric Sandeen 2014-05-13 16:39:09 UTC
btrfs-progs-3.14.1 has been pushed to Fedora 19 and 20 for testing.

I frankly have no idea if this will resolve your bug or not, but if you test it and find that it does, please take the opportunity to close this bug.  :)

Another user experienced a similar problem:

I was partitioning a second hard disk in my system (sda) into sda1 and sda2. Formatted both at btrfs. Labelled sda1 as "backup". Added sda2 to "home".

Comment 15 Fedora End Of Life 2015-05-29 10:43:24 UTC
This message is a reminder that Fedora 20 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 20. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '20'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 20 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Comment 16 Fedora End Of Life 2015-06-29 14:50:23 UTC
Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this

Thank you for reporting this bug and we are sorry it could not be fixed.
