hello,

i have some difficulty in understanding multi-device handling in depth.

as http://btrfs.wiki.kernel.org/index.php/Using_Btrfs_with_Multiple_Devices 
tells,

btrfs can span over multiple devices at the same time. (great feature, btw !)

ok then:
 
mkfs.btrfs -m single -d single  /dev/sdb /dev/sdc - creates a btrfs spanning 
over /dev/sdb and sdc

mount /dev/sdb /btrfs - mounts it

btrfs-vol -b /btrfs - does a rebalancing of all data and metadata

btrfs-vol -r /dev/sdc - removes one of the volumes and redistributes any 
extends in use on sdc to sdb (killer feature!!!)

but what if i want to remove /dev/sdb ? (as that one is in use for the 
mount)

regards
roland
