RAID 5/6 Continues Being Improved For Btrfs With Linux 3.20

Written by Michael Larabel in Linux Storage on 19 February 2015 at 06:39 PM EST. 25 Comments

Chris Mason has sent in his pull request of the Btrfs file-system changes for the Linux 3.20 (4.0?) kernel.

Btrfs in Linux 3.19 brought RAID 5 / 6 support improvements and for this next kernel release the RAID level 5 and 6 support is still baking. Chris shared that there's some RAID 5/6 clean-ups to fix some long-standing issues in the code and to improve the work on top of Linux 3.19.

Besides more Btrfs RAID 5/6 work, there's also some ENOSPC fixes for large Btrfs clusters at Facebook and other code clean-ups and fixes. For most Btrfs users, the Linux 3.20/4.0 release should be a rather basic maintenance update.

More details on the Btrfs file-system changes for this next kernel release can be found via this pull request sent in a short time ago by Chris Mason at Facebook.
