Hi, I just encountered this kernel bug when I executed "btrfs balance start /". I''m sorry if this is not enough data but I couldn''t save the log as my system didn''t respond after the dmesg. It said "kernel bug" before the trace. partial log: http://i.imgur.com/ygk3Nid.jpg Regards, Chris -- Christopher Krooß <c.krooss@gmail.com> -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I don''t know if it adversely affects the file system. I''d either look at 3.12.0-rc3, or regress to 3.10.14 if you need to balance sooner than later. Or wait until several balance related fixes end up in 3.11.x (maybe 3.11.5). If you aren''t using a 3.11 kernel, it might be useful to know what version you are using.

I''m in fact running 3.11.3 so I''ll just wait it out. There were some csum errors after I rebooted, but it seems to just be /var/log/journal.

This bug is fixed with this patch headed to stable. http://www.mail-archive.com/linux-btrfs@vger.kernel.org/msg27549.html Chris Murphy-- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
