Hi list - Can anybody tell me whether btrfs-raid10 reads and writes a stripe at a time, like traditional raid10, or whether it reads and writes individual redundant blocks like btrfs-raid1, but just locks particular disks as mirror pairs, and/or locks the order in which mirror pairs should be written to in sequence? It occurs to me that this might be an important distinction for workloads with very high small random I/O - stripe reads and writes being at a disadvantage to individual blocks being read and written, when the requests are smaller than the stripe. Apologies again if this is a question that should have an obvious answer, but as long as it took me to figure out that btrfs-raid1 is NOT much like traditional raid1, it seemed worth asking. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
