Write hole in RAID 1

Actually, RAID 1 has the same write hole problem as RAID 5 does. Should the power fail after one disk is updated, but the other is not yet updated, and then the first disk fails, there will be data corruption.

As usual, scheduled synchronizations of the array reduce probability of this effect causing any practical trouble.
