Steps for performance testing
Setup cStorPool and StorageClass
- on the number of OpenEBS replicas (1 vs 3) (latency between cStor target and cStor replica)
- on whether all the replicas are in one zone or across multiple zones
- the network latency between the application pod and iSCSI target (cStor target)
Run fio test through OpenEBS Litmus
Clone litmus repository
git clone https://github.com/openebs/litmus.git cd litmus/apps/fio/tests/performance
Edit run_litmus_test.yaml and modify the following
- name: PROVIDER_STORAGE_CLASS value: openebs-standard #value: local-storage - name: APP_NODE_SELECTOR value: percona - name: FIO_TEST_PROFILE value: standard-ssd - name: FIO_SAMPLE_SIZE value: "128m" - name: FIO_TESTRUN_PERIOD value: "60"
Run the fio performance test.
kubectl create -f run_litmus_test.yaml
Observe the results at the end of the test.
