I created a btrfs file system with a single 420 megabyte file in it. And, when I look at the file system with btrfs-debug, I see gigantic extents, as large as 99 megabytes: > $ sudo btrfs-debug-tree /dev/sdb | grep extent > ... > dev extent chunk_tree 3 > dev extent chunk_tree 3 > extent data disk byte 80084992 nr 99958784 > extent data offset 0 nr 99958784 ram 99958784 > extent compression 0 > extent data disk byte 181534720 nr 74969088 > extent data offset 0 nr 74969088 ra...

This series adds an initial implementation for scrub. It works quite straightforward. The usermode issues an ioctl for each device in the fs. For each device, it enumerates the allocated device chunks. For each chunk, the contained extents are enumerated and the data checksums fetched. The extents are read sequentially and the checksums verified. If an error occurs (checksum or EIO), a good copy

Hello, This is the userspace part of restriper, rebased onto the new progs infrastructure. Restriper commands are located under ''balance'' prefix, which is now the top level command group. However to not confuse existing users ''balance'' prefix is also available under ''filesystem'': btrfs [filesystem] balance start btrfs [filesystem] balance

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
