Can you start the raid at all? If it is in degraded mode now then you
can just add the other disks back into the raid1 for each.

If you can't even start degraded mode then I would suggest reformating
one disk, create new raids in degraded mode on it, copy all the data
over from the remaining disk and then add the remaining disk back into
raid1.
