Add '--force' to the 'mdadm --assemble' command. This tells mdadm to try really hard to assemble the array, modifying info in the super blocks if necessary. Be aware that though doing this will normally give you a working array, there may be data corruption within the array (it depends somewhat on the answer to that first important question). I would recommend at least an 'fsck' if that is practical. The array will be assembled degraded. You will need to add in a spare if you are happy that the data is sufficiently intact.
