Would this be akin to dt's "pattern=iot"? From http://www.scsifaq.org/RMiller_Tools/ftp/dt/dt-UsersGuide.pdf : "So, what is DJ’s IOT test pattern? This pattern places the logical block address (lba) in the first word (4 bytes) of each block, with (lba+=0x01010101) being placed in all remaining words in the data block (512 bytes by default). In this way, the logical block is seeded throughout each word in the block." If so what would happen on things like the second pass - e.g. if fio stops how do you know which iteration you were on or is this irrelevant? -- Sitsofe | http://sucs.org/~sits/ -- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
