Unfortunately my laptop deadlocks from time to time, and too often it triggers this bug in btrfs which is quite hard to recover from. The bigger problem is that all the user sees (if anything) is seemingly unrelated info, namely, "RIP: btrfs_num_copies+0x42/0x0b" or somesuch http://marc.merlins.org/tmp/btrfs_num_copies.jpg It''s only if you have serial console, or netconsole, which we can''t really assume the average users to have, that you can get the correct oops and bug info. I lost another 3 hours with many reboots and a...

Hi, The following patches add support for ext4 and btrfs to PV-GRUB. These patches are taken nearly verbatim from those provided by Fedora and Gentoo. We''ve been using these patches for the PV-GRUB images available in EC2 for some time now with no problems. Changes from v1: - Makefile has been changed to check the exit code from patch - The btrfs patch has been rebased to apply

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

Hi all - Here''s my current error handling patchset, against 3.1-rc8. Almost all of this patchset is preparing for actual error handling. Before we start in on that work, I''m trying to reduce the surface we need to worry about. It turns out that there is a ton of code that returns an error code but never actually reports an error. The patchset has grown to 65 patches. 46 of them
