I do have one question so far. Since I was learning, I created a sparse file, and then used mkfs to get a btrfs filesystem. I entertained myself with that for a while, and then decided that I wanted to try out the multi device support. I found that the device add command requires the device to be a block device, and wouldn't accept another sparse file that I had created. Is there a workaround, or is that just the way it is? I ended up just making a logical volume to get the second block device. Thanks for making such a cool fs!
