fio exit run on timeout of device?

fio exit run on timeout of device?

[Slow bucks]

Is there a way to tell FIO to immediately exit if a device times out or 
hangs during a run?

Hi,

Good question. From what I've seen, at the moment it partially depends
on the ioengine. If I/Os somehow timeout from below you might be able
to use max_latency. If they just hang indefinitely the engine can be
become stuck waiting forever..

Hmm....

What do you get if you use iodepth_batch_complete_min=0 and
max_latency=1s with libaio?

max_latency=1s -> Is that in seconds or milliseconds?

Hi,

The answer to that is within the value "1s" itself :-) See
http://fio.readthedocs.io/en/latest/fio_doc.html#cmdoption-arg-max_latency
and http://fio.readthedocs.io/en/latest/fio_doc.html#parameter-types
for why.
