I recently posted a link to a Linux Magazine article about ZFS, now there’s a follow up interview with Chris Mason, Oracle developer and project lead of Btrfs.
How awesome is this?
Chris Mason: Today you can do this:
mkfs.btrfs -m raid1 -d raid10 /dev/sda /dev/sdb /dev/sdc /dev/sdd
And you’ll get metadata on raid1 and data on raid10. The raid10 will use all four drives and the raid1 will use two drives at a time. Yes, btrfs allows you to pick different values for data or metadata.
Sweet.
