[sig-storage] EmptyDir volumes pod should support memory backed volumes of specified size [Suite:openshift/conformance/parallel] [Suite:k8s]

fail [k8s.io/kubernetes.0-rc.0/test/e2e/common/storage/empty_dir.go:362]: failed to match expected string 10240 with 8036340
Expected
    <string>: 8036340

    <string>: 10240

Comment 1 Jan Safranek 2021-09-02 13:49:35 UTC

This seems to affect only OKD. Clearing blocker until we know the root cause.

Comment 2 Jan Safranek 2021-09-02 14:12:41 UTC

The test fails because it expects kubelet v1.22, while the test runs with kubelet 1.21. To be precise, it expects SizeMemoryBackedVolumes feature gate enabled and it's alpha in 1.21 and beta in 1.22.

Running 1.22 tests against 1.21 kubelet is ... not really useful. Feel free to ignore the test or even disable it until you can get 1.22 kubelet to your OS images.

Comment 3 Vadim Rutkovsky 2021-09-02 14:27:06 UTC

Ooh, indeed, we're still at 1.21 kubelet
