The propagation 52ea8dc4b6Seschrock * gets very complicated due to RAID-Z, gang blocks, and vdev caching. We want 53ea8dc4b6Seschrock * to chain together all ereports associated with a logical piece of data. For 54ea8dc4b6Seschrock * read I/Os, there are basically three 'types' of I/O, which form a roughly 55ea8dc4b6Seschrock * layered diagram: 56ea8dc4b6Seschrock * 57ea8dc4b6Seschrock * +---------------+ 58ea8dc4b6Seschrock * | Aggregate I/O | No associated logical data or device 59ea8dc4b6Seschrock * +---------------+ 60ea8dc4b6Seschrock * | 61ea8dc4b6Seschrock * V 62ea8dc4b6Seschrock * +---------------+ Reads associated with a piece of logical data. 63ea8dc4b6Seschrock * | Read I/O | This includes reads on behalf of RAID-Z, 64ea8dc4b6Seschrock * +---------------+ mirrors, gang blocks, retries, etc. 65ea8dc4b6Seschrock * | 66ea8dc4b6Seschrock * V 67ea8dc4b6Seschrock * +---------------+ Reads associated with a particular device, but 68ea8dc4b6Seschrock * | Physical I/O | no logical data. Issued as part of vdev caching 69ea8dc4b6Seschrock * +---------------+ and I/O aggregation. 70ea8dc4b6Seschrock * 71ea8dc4b6Seschrock * Note that 'physical I/O' here is not the same terminology as used in the rest 72ea8dc4b6Seschrock * of ZIO. Typically, 'physical I/O' simply means that there is no attached 73ea8dc4b6Seschrock * blockpointer. But I/O with no associated block pointer can still be related 74ea8dc4b6Seschrock * to a logical piece of data (i.e. RAID-Z requests). 75ea8dc4b6Seschrock * 76ea8dc4b6Seschrock * Purely physical I/O always have unique ENAs. They are not related to a 77ea8dc4b6Seschrock * particular piece of logical data, and therefore cannot be chained together. 78ea8dc4b6Seschrock * We still generate an ereport, but the DE doesn't correlate it with any 79ea8dc4b6Seschrock * logical piece of data. When such an I/O fails, the delegated I/O requests 80ea8dc4b6Seschrock * will issue a retry, which will trigger the 'real' ereport with the correct 81ea8dc4b6Seschrock * ENA. 82ea8dc4b6Seschrock * 83ea8dc4b6Seschrock * We keep track of the ENA for a ZIO chain through the 'io_logical' member. 84ea8dc4b6Seschrock * When a new logical I/O is issued, we set this to point to itself.
