Let's assume that data gets corrupted on disk. I understand that on reads this would perhaps result in checksum mismatches and can get corrected. Does Mapr FS do anything in the background to correct this if this piece of data is never accessed? In short my question is if checksum mismatch handling the only way corrupt data is fixed?
