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
