That's the reconstruction algorithm. It reads each stripe and if it has a bad parity, the parity data gets rewritten.That's the way parity re-write works. I thought reconstruction worked differently. oster@?
Reconstruction does not do the "read", "compare", "write" operation like parity checking. It just does "read", "compute", "write". In the case of RAID 1, "compute" does nothing ,and it's basically read from one component and write to the other.
