The `fio` test utilises the [fio tool](https://github.com/axboe/fio), configured
to perform measurements upon a single test file.
The `fio` test utilizes the [fio tool](https://github.com/axboe/fio), configured to perform measurements upon a single test file.
The test configuration used by the script can be modified by setting a number of
environment variables to change or over-ride the test defaults.
The test spawns 8 jobs that exercise the I/O types `sequential read`, `random read`, `sequential write` and `random write`, while collecting
data using a block size of 4 Kb, an I/O depth of 2, and uses the `libaio` engine on a workload with a size of 10 gigabytes for a period of
10 seconds on each I/O type.
## DAX `virtio-fs` `fio` Kubernetes tests
The results show the average bandwidth and average number of IOPS per I/O type in JSON format.
[Test](fio-k8s/README.md) to compare the use of DAX option in `virtio-fs`.
The `fio` test can be run by hand, for example:
```
$ cd metrics
$ bash storage/fio_test.sh
