Hi,

Can someone shed some light on how BTRFS will manage a bunch of disks of 
varying size for the planned raid5/6. e.g. 3x 2TB disk and 1x 250GB 
disk? If using a raid5 setup will a 750GB of usable data automatically 
be used as a 4 disk raid5 while the rest is used as a 3 disk raid5?! If 
so; how do you control what files are on the "speedy" section of the volume?
