With MeeGo using Btrfs by default, Canonical making plans for Btrfs in as soon as Ubuntu 10.10, and Novell now pushing Btrfs in openSUSE, among other milestones for this advanced Linux file-system, we decided to see where the Btrfs performance is now at with the Linux 2.6.35 kernel that's currently in development.

Mason said he would like to see Btrfs ultimately replacing existing Linux filesystems like the popular Ext3 and Ext4 systems that are often the default on enterprise Linux distributions.

Like Fedora 13, Fedora 14, the latest version of Fedora, has support for btrfs. However, it is not enabled out of the box, that is, it is not available as a File System Type option, if you did not edit the boot method to include btrfs. This post offers a very simple guide on how to pass the btrfs option to Fedora 14.

This tutorial will explain you how to boot from a BTRFS filesystem with kernel 2.6.31-RC4 and BTRFS 0.19. BTRFS is a new filesystem with some really interesting features like online defragmenting and snapshots. BTRFS is an experimental filesystem, use at your own risk. The kernel used is also experimental.

Yesterday we reported that Ubuntu 10.10 gained Btrfs installation support and since then we have been trying out this Btrfs support in Ubuntu "Maverick Meerkat" and have a fresh set of Btrfs benchmarks to serve up.

This guide shows how to work with the btrfs file system on Linux. It covers creating and mounting btrfs file systems, resizing btrfs file systems online, adding and removing devices, changing RAID levels, creating subvolumes and snapshots, using compression and other things.

Earlier this week we reported that Ubuntu has plans for the Btrfs file-system in 2011 and 2012 by providing support for installing Ubuntu Linux to a Btrfs file-system. This information was based upon documents coming out of the Ubuntu Developer Summit in Brussels, but it turns out that Canonical may actually deploy Btrfs this year.

Btrfs is a new copy on write filesystem for Linux aimed at implementing advanced features while focusing on fault tolerance, repair and easy administration. Initially developed by Oracle, Btrfs is licensed under the GPL and open for contribution from anyone.

This tutorial explains how you can revert failed apt operations (like apt-get upgrade) and roll back to the previous system state with apt-btrfs-snapshot on an Ubuntu 12.10 system that uses the btrfs file system. apt-btrfs-snapshot creates a snapshot of the system before the apt operation.
