If the Manage disk redundancy page gives the message "The free disk count must equal one" and "Manual intervention may be required", then you likely will have additional hard drives that need to be disconnected while the RAID is set up. An external USB drive will have this effect, and should be unplugged.

Note: the addition of another drive is restricted to a RAID 1 scenario, i.e. two hard drives only (/dev/hda and /dev/hdc or their SATA equivalent). The addition of a third drive to a RAID 1 (i.e. a spare) is not recognized by the system [[bugzilla:6907]]
