pierreozoux/fio repository overview

⁠Procedure to test your performances

Fork the project and create your test folder in results folder. Name it, as you feel appropriate.

⁠README

Create a README.md file to help other get a sense of your setup, you can take a look at other folders.

⁠Hardware

First to help other, we need to know which kind of hardware you use:

hwinfo --disk > ./hw

⁠Network performance

Evaluate the network performance between pods and ceph cluster nodes. We'll use iperf for that.

iperf -s
iperf -c $IP -i1 -t 10 > net

⁠RAW disk performance

From the host, format your disk, mount it on /mnt/disk/ and run:

docker run -it -v /mnt/disk:/test pierreozoux/fio > raw

⁠CEPH volume performance

⁠Procedure to setup the cluster

Once you have deployed the rook operator as described in the documentation⁠, please proceed to deploy the same cluster:

kubectl create -f k8s/rook-cluster.yaml
kubectl create -f k8s/rook-storageclass.yaml

The important parameter here are:

• hostNetwork to avoid testing overlay network
• replica set to 2

⁠Test performances

Once your cluster is running and healthy:

kubectl create -f k8s/test.yaml

⁠PR

You can now PR, and compare to others.
