Kernel Log: Coming in 2.6.32 (Part 3) - Storage

"A number of changes to the block layer promise better data throughputs and reactivity. There are also several new drivers for storage hardware.

"Linux kernel 2.6.32-rc7 hit the streets late last week, but when 2.6.32 will finally be released remains anyone's guess. There are likely to be at least one, more likely two, further pre-release versions in this development cycle, a cycle which has been slightly disrupted by typos and the Kernel Summit. Following on from our reviews of the changes in the networking and graphics hardware subsystems, this instalment of the Kernel Log 2.6.32 series looks at file systems and storage.

"Btrfs

"There have been a whole heap of changes to Btrfs. The experimental "next generation file system for Linux" can now write at more than 1 GB per second on fast hardware and now matches XFS for speed on our test system. Btrfs' previous maximum data transfer speed was 400 MB per second, as this maxed out CPU usage. Snapshots and subvolumes can now be renamed in Btrfs and can be deleted much more rapidly. Thanks to various enhancements, RPM and Yum now also work faster."
