FIO failed with error code 84

[wangyihanlarry]

HI,

I have ran a following fio files which failed always with erro code 84, there are two files sdb1.163874340864.hdr_fail and local-sdb1-192G-0-verify.state got generated, I can check the content with sdb1.163874340864.hdr_fail(in below), however, I have no clue on how to check the state file? and what is the issue met during the IO, any advice?

error is like: verify: bad header rand_seed 2755570710099588192, wanted 2447201393907302329 at file /dev/sdb1 offset 163874340864, length 8192 (requested block: offset=163874340864, length=8192)
hdr_fail data dumped as sdb1.163874340864.hdr_fail
