Seems like it can't parse the partition table of the assembled disk.
Look in /var/log/messages for more clues and make sure that the
/dev/mapper/via_cdjiceidbi device is the size it's supposed to be.

That entry represents the entire (virtual) disk where no filesystems reside.
You need to get the partition table parsed correctly first before
mounting any filesystems.
