This experiment upgrades the zfs-localpv driver components from any previous version to the latest desired stable version or to the develop branch ci images.
- Do not provision/deprovision any volumes during the upgrade, if we can not control it, then we can scale down the openebs-zfs-controller stateful set to zero replica which will pause all the provisioning/deprovisioning request. And once upgrade is done, the upgraded Driver will continue the provisioning/deprovisioning process.
## Exit-Criteria
- zfs-driver should be upgraded to desired version.
- All the components related to zfs-localpv driver including zfs-controller and csi node-agents should be running and upraded to desired version as well.
- All the zfs volumes should be healthy and data prior to the upgrade should not be impacted.
- After upgrade we should be able to provision the volume and other related task with no regressions.
## How to run
- This experiment accepts the parameters in form of kubernetes job environmental variables.
- For running this experiment of upgrading zfs-localpv driver, clone openens/zfs-localpv[https://github.com/openebs/zfs-localpv] repo and then first apply rbac and crds for e2e-framework.
To get the test-case result, get the corresponding e2e custom-resource `e2eresult` (short name: e2er ) and check its phase (Running or Completed) and result (Pass or Fail).
```
kubectl get e2er
kubectl get e2er upgrade-zfs-localpv -n e2e --no-headers -o custom-columns=:.spec.testStatus.phase
kubectl get e2er upgrade-zfs-localpv -n e2e --no-headers -o custom-columns=:.spec.testStatus.result
