After further investigation, it appears as though this affects the Live CD only. The alternate install works perfectly with RAID array creation even when Ubuntu is installed.
It appears as though the Live CD does not officially support software RAID array creation, see: https://help.ubuntu.com/community/Installation/SoftwareRAID#Requirements Though this is not made apparent to the user when creating the RAID array (gnome-disk-utility is there and it allows you to get as far as configuring the array). -- RAID creation fails due to absent package "mdadm" https://bugs.launchpad.net/bugs/440831 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
