If it cannot read them, it won't assemble the array. Depending on the type of array, you could --build the array instead. This allows for arrays that deliberately don't have superblocks. It should work for raid0, might work for linear, could work for raid1, but no for anything else. If you want to try it, send me the --examine output. and I'll suggest a command.
