Public bug reported: Doing a fresh kubuntu precise install with the following setup:
VirtualBox 4.0.14 /dev/sda 32 GB /dev/sda1 384 MB btrfs /dev/sda2 2 GB swap /dev/sda3 max btrfs /dev/sdb 32 GB /dev/sda1 384 MB btrfs /dev/sda2 2 GB swap /dev/sda3 max btrfs I would jump into a shell, run fdisk and then create the partitions then format them: mkfs.btrfs -d raid1 -m raid1 /dev/sda1 /dev/sdb1 mkfs.btrfs -d raid1 -m raid1 /dev/sda3 /dev/sdb3 Then launching the installer and trying to configure the installer to use /dev/sda1 for /boot and /dev/sda3 for / gets the following error. I leave /dev/sdb* alone but btrfs will mirror the data there.
