fio exit run on timeout of device?
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?

max_latency=1s
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.
