Btrfs RAID Support For RAID 5/6 Is Improving - Phoronix
Btrfs RAID Support For RAID 5/6 Is Improving Written by Michael Larabel in Linux Storage on 17 November 2014 at 10:12 AM EST. 2 Comments Of the RAID 0/1/5/6/1+0 levels supported natively by the Btrfs file-system, it's been the RAID 5 and RAID 6 implementations that have been deemed experimental and not yet production ready. Fortunately, that may soon be changing with some fresh Btrfs tool patches.

Docker and btrfs
As I write this the first Docker convention is going on in San Francisco (sounds funny to write it was â€œdocker conventionâ€ instead of â€œdockerconâ€â€¦a convention sounds like a scene from Fear and Loathing in Las Vegas), and Docker has hit 1.0 and been declared production worthy. Docker has had, for a few versions, the ability to use btrfs as itâ€™s backing driver, instead of aufs. Install btrfs on Ubun
