Hello everyone, Btrfs v0.14 is now available for download. Please note the disk format has changed, and it is not compatible with older versions of Btrfs. For downloads and documention, please see the Btrfs project page: http://btrfs.wiki.kernel.org The oss.oracle.com Btrfs project page will soon start redirecting here. v0.14 has a few performance fixes and closes some races that could have allowed corrupted metadata in v0.13. The major new feature is the ability to manage multiple devices under a single Btrfs mount. Raid0, raid1 and raid10 are supported. Even for single device filesystems, metadata is now duplicated by default. Checksums are verified after reads finish and duplicate copies are used if the checksums don't match. Multi-device design details can be found here: http://btrfs.wiki.kernel.org/index.php/Multiple_Device_Support And sample usage to create and add volumes can be found here: http://btrfs.wiki.kernel.org/index.php/Using_Btrfs_with_Multiple_Devices I'm putting up some benchmarks of the new multi-device code as the runs finish: http://btrfs.wiki.kernel.org/index.php/Multi-device_Benchmarks Next up on the Btrfs todo list is finishing off the device removal and IO error handling code. After that I'll add more fine grained locking to the btrees. Thanks to everyone who has helped contribute to and test this release. -chris -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
