Discussion:
What happened: The CSI hostpath driver used in the e2e tests expects the root directory of nodes to be set to , , however nodes can be configured to use different paths. The tests should find out the root directory from kubelet to allow for this. Several test failures related to CSI Volumes: What you expected to happen: Test should be expected to pass. How to reproduce it (as minimally and precisely as possible): Configure kubelet on cluster nodes to use the non-default path. Run the storage-csi e2e tests. Anything else we need to know?: Environment: Kubernetes version (use ):Cloud provider or hardware configuration: OS (e.g: ): Kernel (e.g. ): Install tools: Network plugin and version (if this is a network-related bug): Others:

How? I've asked about that before and the conclusion was that there is no portable way to do that (i.e. no official API). It seems to fall onto cluster admins to configure CSI driver deployments so that this particular aspect matches the cluster. For the tests that means that there has to be a parameter for the kubelet data directory that users of then have to set.
We could add and respect a flag of course then all nodes have to be the same at least. Reminder though
That's indeed another complication.

/remove-lifecycle stale Tracked for csi-driver-host-path in There's a bigger issue about both mock and hostpath driver in which includes "support non-default kubelet path".
The current hostpath driver in k/k testing supports non-default paths, but the suite doesn't use that yet.
