Issue

• During the initial stages of anaconda, if I switch to a virtual terminal and set up an mdraid device manually using the ddf metadata format, anaconda presents an exception and traceback.

• mdraid crashes during installation if the RAID volumes have metadata iin the DDF format on Intel Pattsburg systems. This is irrespective of whether the volume was created from LSI BIOS utility and volumes were imported or volumes were created using “mdadm with metadata type as DDF.

• I get an exception in anaconda:
