There is no coordination between Fedora mdadm usage and Ubuntu mdadm usage. In particular, there are different superblock versions that are likely in use and different methods of numbering arrays. Fedora is switching away from numbering arrays entirely and going to name based array recognition. It's possible that something in our mdadm usage caused the superminor number in your existing arrays to get updated, resulting in this change in names, but this sort of cross distro interaction is not likely something I can properly debug (especially as I don't even know what the live USB image does to bring the arrays up). If anyone can fix this, it's likely going to have to be the live image people, not me.
