As a test I want to install Ubuntu 11.10 onto a btrfs file system in raid10 mode.
However, I have no clue on how I should go about that.
I have tried the installer, and then creating the fs in the terminal. However, that didn't work out.
When I went back to the graphical interface I couldn't install. Because it didn't have any mount points.
So, how should I do this?
After using the alternate installer and dropping to a shell I did the following:
mkfs.btrfs -m raid10 -d raid10 /dev/sda /dev/sdb /dev/sdc /dev/sdd
then you also need to run:
btrfs dev scan
Then when choosing the partition to install to, select one of the above and mount that to /. Leave all partitions untouched.
This installs the system, however, installing the bootloader fails...
