Hi, my system suddenly crashed and gave me this dump: http://imgur.com/oO6S0 I checked and there is not btrfs commit in linus'' tree since I compiled this kernel. Gustavo

Hello, I''m seeing a lot of warnings in dmesg with a BTRFS filesystem. I''m using the 3.1 kernel, I found a patch for these warnings ( http://marc.info/?l=linux-btrfs&m=131547325515336&w=2) <http://marc.info/?l=linux-btrfs&m=131547325515336&w=2>, but that patch has already been included in 3.1. Are there any other patches I can try? I''m using

After running ceph on XFS for some time, I decided to try btrfs again. Performance with the current "for-linux-min" branch and big metadata is much better. The only problem (?) I''m still seeing is a warning that seems to occur from time to time: [87703.784552] ------------[ cut here ]------------ [87703.789759] WARNING: at fs/btrfs/inode.c:2103

An user reported that he has hit an annoying deadlock while playing with ceph based on btrfs. Current updating device tree requires space from METADATA chunk, so we -may- need to do a recursive chunk allocation when adding/updating dev extent, that is where the deadlock comes from. If we use SYSTEM metadata to update device tree, we can avoid the recursive stuff. Reported-by: Jim Schutt

This is a first draft of a subvolume quota implementation. It is possible to limit subvolumes and any group of subvolumes and also to track the amount of space that will get freed when deleting snapshots. The current version is functionally incomplete, with the main missing feature being the initial scan and rescan of an existing filesystem. I put some effort into writing an introduction into

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
