The propagation 54ea8dc4b6Seschrock * gets very complicated due to RAID-Z, gang blocks, and vdev caching. We want 55ea8dc4b6Seschrock * to chain together all ereports associated with a logical piece of data. For 56ea8dc4b6Seschrock * read I/Os, there are basically three 'types' of I/O, which form a roughly 57ea8dc4b6Seschrock * layered diagram: 58ea8dc4b6Seschrock * 59ea8dc4b6Seschrock * +---------------+ 60ea8dc4b6Seschrock * | Aggregate I/O | No associated logical data or device 61ea8dc4b6Seschrock * +---------------+ 62ea8dc4b6Seschrock * | 63ea8dc4b6Seschrock * V 64ea8dc4b6Seschrock * +---------------+ Reads associated with a piece of logical data. 65ea8dc4b6Seschrock * | Read I/O | This includes reads on behalf of RAID-Z, 66ea8dc4b6Seschrock * +---------------+ mirrors, gang blocks, retries, etc. 67ea8dc4b6Seschrock * | 68ea8dc4b6Seschrock * V 69ea8dc4b6Seschrock * +---------------+ Reads associated with a particular device, but 70ea8dc4b6Seschrock * | Physical I/O | no logical data. Issued as part of vdev caching 71ea8dc4b6Seschrock * +---------------+ and I/O aggregation. 72ea8dc4b6Seschrock * 73ea8dc4b6Seschrock * Note that 'physical I/O' here is not the same terminology as used in the rest 74ea8dc4b6Seschrock * of ZIO. Typically, 'physical I/O' simply means that there is no attached 75ea8dc4b6Seschrock * blockpointer. But I/O with no associated block pointer can still be related 76ea8dc4b6Seschrock * to a logical piece of data (i.e. RAID-Z requests). 77ea8dc4b6Seschrock * 78ea8dc4b6Seschrock * Purely physical I/O always have unique ENAs. They are not related to a 79ea8dc4b6Seschrock * particular piece of logical data, and therefore cannot be chained together. 80ea8dc4b6Seschrock * We still generate an ereport, but the DE doesn't correlate it with any 81ea8dc4b6Seschrock * logical piece of data. When such an I/O fails, the delegated I/O requests 82ea8dc4b6Seschrock * will issue a retry, which will trigger the 'real' ereport with the correct 83ea8dc4b6Seschrock * ENA. 84ea8dc4b6Seschrock * 85ea8dc4b6Seschrock * We keep track of the ENA for a ZIO chain through the 'io_logical' member. 86ea8dc4b6Seschrock * When a new logical I/O is issued, we set this to point to itself. Child I/Os 87ea8dc4b6Seschrock * then inherit this pointer, so that when it is first set subsequent failures 88ea8dc4b6Seschrock * will use the same ENA. If a physical I/O is issued (by passing the 89ea8dc4b6Seschrock * ZIO_FLAG_NOBOOKMARK flag), then this pointer is reset, guaranteeing that a 90ea8dc4b6Seschrock * unique ENA will be generated. For an aggregate I/O, this pointer is set to 91ea8dc4b6Seschrock * NULL, and no ereport will be generated (since it doesn't actually correspond 92ea8dc4b6Seschrock * to any particular device or piece of data). 93ea8dc4b6Seschrock */ 94ea8dc4b6Seschrock void 95ea8dc4b6Seschrock zfs_ereport_post(const char *subclass, spa_t *spa, vdev_t *vd, zio_t *zio, 96ea8dc4b6Seschrock uint64_t stateoroffset, uint64_t size) 97ea8dc4b6Seschrock { 98ea8dc4b6Seschrock #ifdef _KERNEL 99ea8dc4b6Seschrock nvlist_t *ereport, *detector; 100ea8dc4b6Seschrock uint64_t ena; 101ea8dc4b6Seschrock char class[64]; 102ea8dc4b6Seschrock 103ea8dc4b6Seschrock /* 104ea8dc4b6Seschrock * If we are doing a spa_tryimport(), ignore errors. 105ea8dc4b6Seschrock */ 106ea8dc4b6Seschrock if (spa->spa_load_state == SPA_LOAD_TRYIMPORT) 107ea8dc4b6Seschrock return; 108ea8dc4b6Seschrock 109ea8dc4b6Seschrock /* 110ea8dc4b6Seschrock * If we are in the middle of opening a pool, and the previous attempt 111ea8dc4b6Seschrock * failed, don't bother logging any new ereports - we're just going to 112ea8dc4b6Seschrock * get the same diagnosis anyway. 113ea8dc4b6Seschrock */ 114ea8dc4b6Seschrock if (spa->spa_load_state != SPA_LOAD_NONE && 115ea8dc4b6Seschrock spa->spa_last_open_failed) 116ea8dc4b6Seschrock return; 117ea8dc4b6Seschrock 118ea8dc4b6Seschrock /* 119ea8dc4b6Seschrock * Ignore any errors from I/Os that we are going to retry anyway - we 1203d7072f8Seschrock * only generate errors from the final failure.
