Documented at <https://wiki.ubuntu.com/KarmicKoala/ReleaseNotes#Automatic%20boot%20from%20a%20degraded%20RAID%20array%20not%20configured%20upon%20installation>:

The installer option to support "boot from a degraded array" does not properly configure the installed system. To correct this after installation, run {{{dpkg-reconfigure mdadm}}} after installation and select the option again. (Bug:462258)
