It's the data which customers read that can be wrong. So it's a

But did you get similar report from customer from the past years? I am not
sure it is reasonable to expect the md5sum should be match under such
conditions (multiple processes do write/read with recovery in progress).
Maybe the test launched 32 processes in parallel is another factor, not
sure
it still happens with only 1 process which means only do read after write.
May I ask if these processes write the same file with same offset? It's
insane if they do... If not, this cound be a problem.
Anyway, I think io accounting is irrelevant.
Yes, I can't figure out why io accounting can be involved.
