Re: kernel BUG at fs/btrfs/relocation.c:1060 during rebalancing
hi, i've got the same problem kernel BUG at fs/btrfs/relocation.c:1060. this was solved by patching the kernel with following patch https://git.kernel.org/cgit/linux/kernel/git/josef/btrfs-next.git/commit/?id=b6c60c8018c4e9beb2f83fc82c09f9d033766571 i've also found, that this patch is NOT included in 3.11.x stable kernel tree. see here to confim the absence https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/tree/fs/btrfs/relocation.c?id=refs/tags/v3.11.4 fous 2013/10/7 Guenther Starnberger linux-bt...@gst.priv.at: On Thu, Sep 26, 2013 at 07:26:07AM +0200, Guenther Starnberger wrote: Yes - this also happens on 3.12-rc kernels.

kernel BUG at fs/btrfs/relocation.c:1060 during rebalancing
On one of my btrfs filesystems I'm encountering a reproducable kernel bug during rebalancing. This issue originally appeared on Linux 3.11.1, but I am also able to reproduce it in a VM using btrfs-next (c024ca6) and Linux 3.12-rc2 (4a10c2a). I did the following operations (in chronological order) on the filesystem before this issue appeared, so they might be responsible for putting the filesystem into a bad state. However, according to fsck the filesystem looks fine. - Regular deduplications with bedup. - Mounting the previously uncompressed filesystem with the lzo compression option and then using defrag to defrag (and compress) each file. - Running out of diskspace during a bedup run with size cutoff 0, although the actual disk usage should be less than 50%. Based on the suggestions in the FAQ (http://goo.gl/qCgZR) I decided to try rebalancing the filesystem. - Rebalance the filesystem (btrfs fi balance /mountpoint -dusage=5) which lead to the kernel bug. Subsequent rebalancing runs after reboots and with different kernel versions exhibit the same problem.
