Public bug reported: After freshly building a raid 10 using mdadm I copied about a hundred GB of data to the raid. When I check iostat output the numbers read are WAY over the numbers written in only a few minutes after copying. Also being raid 10 the written amount should be about equal, they are wildly different, which to me looks more like random reads.
