Re: Proper way to shut down FIO in Linux

Hey,

Why do you want to kill fio ? That sounds weird to me.

If you need to run your benchmark on constant time then use time_based & runtime instructions.

Objet: Proper way to shut down FIO in Linux

I'm using FIO to run IOs to a number of block devices.  I'm looking for
the proper way to shut down all the threads that are spawned.

I'm doing the following:

/usr/bin/pkill --signal INT fio

Most of the time this works fine, but I do have cases where some of the
FIO processes remain open.  Eventually I get a 300s timeout and then
they're killed.

A couple questions:

1.	When these threads have to be ungracefully killed, do the results
still get counted in the output file?
a.	I'm using JSON output file
2.	Is there a better way I should be killing all the threads?
