Er, Hoyle... I am trying to create a multi-device BTRFS system using two identical drives. I want them to be raid 0 for no redunancy, and a total of 4TB. But in the wiki it says nothing about using fdisk to set up the drive first. It just basically says for me to: mkfs.btrfs -m raid0 /dev/sdc /dev/sdd Seems to me that for mdadm I had to set each drive as a raid member, assemble the array, then format. Is this not the case with BTRFS? Also in the wiki it says "After a reboot or reloading the btrfs module, you'll need to use btrfs device scan to discover all multi-device filesystems on the machine". Is this not done automatically? Do I have to set up some script to do this?
