It's the data which customers read that can be wrong. So it's a dangerous thing. Because customers use the data directly. If it's true it looks like there is a race between non aligned read and recovery process.
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. Anyway, I think io accounting is irrelevant.
