Does anyone know of GOOD CLI driven stress testing tools that are not
just benchmarks?
I looked at IOZone and some things like that, but they seem more
geared to running up some load and then making pretty graphs.
I am interested in actual testing tools that will do things like:
* async reads and writes to disk
* raw disk I/O
* large file I/O
* random file chunk I/O
I want them to do a LOT of I/O, preferably simultaneously
(multi-threaded) and compare written data to expected data, and return
pass/fail criteria, not benchmark numbers. I'm more interested in
functional testing rather than pure performance testing.
So I wanted to see if any of you knew of good filesystem or disk
testing tools that would meet the need.
Also, tools need to be completely configurable from CLI, and have to
be able to target specific block devices or mounted filesystems. I
looked at a tool simply called Stress earlier, which does a lost of
what I want it to do, but has no obvious way of specifying a device to
test against. It's more of a system-wide stress tool rather than a
targeted one.
Any ideas?
Cheers
Jeff
