While testing raid-auto-repair patches I''m going to send out later, I just found the very last bug in my current scrub patch series: Changelog v4->v5: - fixed a deadlock when fixup is taking longer while scrub is about to end Original message follows: ------------------------ This patch set introduces two new features for scrub. They share the backref iteration code which is the

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

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

Changes v1-v2: - Remove restriction that BTRFS_IOC_GET_DEVICE_STATS is a privileged operation - Cast u64 to unsigned long long for printf() Changes v2-v3: - Rebased on Chris'' current master Changes v3-v4: - Add padding at end of ioctl structure Changes v4-v5: - The statistic members in the ioctl are now organized as an array of 64 bit values. Symbolic names for the array indexes

Hi: I'm in the middle of recoverying from a tactical error copying around an Mac OS X 10.10.5 Time Machine backup (turns out Apple's instructions aren't great...), and I had rsync running for the past 6 hours repairing permissions/acls on 1.5 TB of data (not copying the data), and then it just died in the middle with: .L....og.... 2015-03-11-094807/platinum-bar2/usr/local/mysql

Hi gang, I was a little surprised to see that patch go by recently which fixed an endian bug. I went to see how sparse checking looked and it was.. broken. I got it going again in my Fedora environment. Most of the patches are just cleanups, but there *were* three real bugs lurking in all that sparse warning spam. So I maintain that it''s worth our time to keep it going and fix

The biggest one is a fix for fstrim, and there''s a fix for on-disk free space cache. Others are small fixes and cleanups. The last three have been sent weeks ago. The patchset is also available in this repo: git://repo.or.cz/linux-btrfs-devel.git for-chris Note there''s a small confict with Al Viro''s vfs changes. Li Zefan (11): Btrfs: add pinned extents to

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

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
