Sounds like a modification of the "replace" code to allow replacing the with self-same drive. Something like "want_refresh" would mark the drive as a soft replacement to mark that slot to be re-written. But if the drive is expected to be "weak" you could just rotate in a spare drive without degrading the array with the existing code. -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
