That depends on if you did a "check" or a "repair" - see the SCRUBBING
AND MISMATCHES section of the md(4) man page:
"If check was used, then no action is taken to handle the mismatch,
it is simply recorded. If repair was used, then a mismatch will
be repaired in the same way that resync repairs arrays."
Good luck,
