From: Anand <anand.jain@oracle.com> This patch adds creation-time to the snapshot list display, which would help user to better manage the snapshots when number of snapshots grow substantially. This patch is developed and on top of the send/receive btrfs and btrfs-progs repo at git://github.com/ablock84/linux-btrfs.git (send-v2) git://github.com/ablock84/btrfs-progs.git (send-v2)

Hi Linus, My for-linus branch has a one line fix: git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus Sage hit a deadlock with ceph on btrfs, and Josef tracked it down to a regression in our initial rc1 pull. When doing nocow writes we were sometimes starting a transaction with locks held. Josef Bacik (1) commits (+1/-0): Btrfs: release path before starting

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

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

First two patches are trivial cleanups that I''ve spotted while reading send.c, can be applied independently. The third patch contains the important bits, safety checks that the subvolumes involved in send do not accidentally lose the RO status. I haven''t seen this documented anywhere that this is mandatory, implied from how I assume send works. Please let me know if this is

This is the next patch series for scrub userland tools. Change log v1->v2: - commands now reachable as "btrfs scrub ..." instead of "btrfs filesystem scrub ..." - ability to scrub a single device instead of a whole file system - superfluous command line options removed - resume is now a separate command ("scrub resume") instead of "scrub start -r" -

The goal is to detect when drives start to get an increased error rate, when drives should be replaced soon. Therefore statistic counters are added that count IO errors (read, write and flush). Additionally, the software detected errors like checksum errors and corrupted blocks are counted. An ioctl interface is added to get the device statistic counters. A second ioctl is added to atomically get
