I've just run into this myself and so can confirm this issue on a btrfs
filesystem with 2 devices, where it is created by doing:
mkfs.btrfs -m raid1 /dev/sda10 /dev/sda11
modprobe btrfs
btrfsctl -a
mount /dev/sda10 /home
The df command shows it has twice the space I was expecting (61GB rather than
30GB). The btrfs-show command shows that it has two devices but doesn't
appear to contain any way to show the RAID level implemented. I get the
same outcome if I mount /dev/sda11 instead of sda10.
Any ideas ?
Chris
