When I did try it just that way, it failed completely. I created the structure, except that I put quotas on each of the subvolumes, and then I rsynced the files from my non-btrfs copies which I had to do offline using my grml cd, and when I rebooted back into the new arrangements, it was a mess. I also got advice from their mailing list that I might want separate pools and this is why I was wondering about lvm, since I don't want partitions again. -- Your life is like a penny.
