Is a valid test scenario to run block e2e test on IBM (it never worked for me)? Ref https://github.com/openshift/oadp-operator/blob/master/tests/e2e/backup_restore_suite_test.go#L396 |
|
@mateusoliveira43 yes this should help with the block e2e on IBM Cloud. Testing block volume app on IBM Cloud would certainly help here. |

PR updated for host-plugins path changes for node-agent. PTAL ! |

I think this should be deleted
what IBM changes is just host-plugins path, no?

I think yesterday in scrum we discussed that we need both.

I recall both are needed to allow a symlink to work. Pod and Host iiuc
There was a problem hiding this comment.
what I remember was that we need to mount both /var/lib/kubelet and /var/data/kubelet on pod
I tested only changing host-plugins path and e2e block datamover worked for me in IBM (which never worked before)
If we need both, then velero docs are still wrong https://velero.io/docs/v1.14/csi-snapshot-data-movement/#configure-node-agent-daemonset-spec

yeah we might need to update the docs upstream, I will do that once this PR is completed.

@weshayutin I will build and try the changes. |

thank you sir! |
Changes look good. node-agent config is as expected on IBM Cloud. Status is healthy. And node-agent pods have access to the volumes directly. DataUpload successful For as little as it matters, you have my approval for this change. |

are we adding this to all tests?
if yes, I would append it to test clientObjects inside t.Run

I think this is fine. Having a clientObject arg for each test case makes this future proof. We might need/write some specific test cases in the future that might need object mocking on per test case basis. And having clientObject array helps in that scenario.

Why the changes were made
The default hostpath /var/lib/kubelet/pods cannot find PersistentVolumeClaims with volumeMode: Block on host.
The correct hostpath for OpenShift on IBM Cloud is /var/data/kubelet/pods
Similarly for host-plugins the correct hostpath is /var/data/kubelet/plugins
We are adding the ability to check for OpenShift infrastructure and update the hostpath and hostplugins for node-agent daemonset in case of OpenShift on IBMCloud
Note: The hostpath set via operator CSV env vars will take precedence (
RESTIC_PV_HOSTPATHandFS_PV_HOSTPATH)Similarly for host-plugins CSV env var will take precedence (
PLUGINS_HOSTPATH)How to test the changes made
/var/data/kubelet/pods/var/lib/kubelet/podsFollow the same steps as above for host-plugins path:
var/data/kubelet/pluginsvar/lib/kubelet/plugins
