If a bit has flipped on a parity stripe and thus the parity is inconsistent. When I pop out a disk
and put it back in, the array is going to be written from parity data that is not quite right. (The
problem I believe you were talking about where you have two identical disks and one is inconsistent,
which one do you read from? is similar). And thus the reconstructed array is going to have different
contents to the array before I failed the disk.
Therefore it should show the error. No?
