Hi list,
I want to create volumes (not subvolumes) on one device.
Could it work?
If it works, how can I do by btrfs tools ?
If it can't, is there any way to create subvolumes which have their independent space?
For example, I want to create 100MB for /home and 50 MB for /root.
thanks,

Short version: No. For that particular purpose, currently you'd better
stick with wither LVM+ext4 or zfs.
Long version: IIRC Arne Jansen posted patches for subvolume/qgroup
quota support, so it can be used for what you need, up to a certain
degree. It's not as complete as zfs (which also supports reservation
in addition to quota), and it hasn't reached upstream kernel yet (at
least it's not in 3.1-rc9).
