Hey there,

The CSI driver in this repository is built with OpenShift in mind, and does not have an upstream that is intended to work with vanilla Kubernetes. Even if you get it to work now, it may break in the future.

We have had some discussions around reviving the upstream for the CSI driver, which is located here: https://github.com/oVirt/csi-driver

We are also doing a fair bit of work which will make the process easier here: https://github.com/oVirt/go-ovirt-client

However, at this time we haven't made any progress that would be useful to you. With that in mind, I would recommend reporting possible bugs either on GitHub or on Bugzilla, that way they will reach us quicker, even if we officially don't support vanilla Kubernetes.

Cheers,

Janos

Hi all,

I deployed ovirt-csi in the k8s by applying yaml manually. I used the latest version of the container image.
(https://github.com/openshift/ovirt-csi-driver-operator/tree/master/assets)

After successfully creating pvc and pod, I tried to delete it.
And the pod is deleted, but the pvc is not deleted. This is because deleting a pod does not unmap /dev/rbd0 attached to the ovirt vm.

How can I delete the pvc successfully?

oVirt engine version is 4.4.7.6-1.el8.
Here is the engine log when deleting the pod:
