looking into the 5 control plane replica test and I saw some failures related to in-tree ephemeral volumes: Failing tests: [sig-storage] In-tree Volumes [Driver: gcepd] [Testpattern: Generic Ephemeral-volume (default fs) (immediate-binding)] ephemeral should create read-only inline ephemeral volume [Suite:openshift/conformance/parallel] [Suite:k8s] [sig-storage] In-tree Volumes [Driver: gcepd] [Testpattern: Generic Ephemeral-volume (default fs) (immediate-binding)] ephemeral should create read/write inline ephemeral volume [Suite:openshift/conformance/parallel] [Suite:k8s] [sig-storage] In-tree Volumes [Driver: gcepd] [Testpattern: Generic Ephemeral-volume (default fs) (immediate-binding)] ephemeral should support two pods which have the same volume definition [Suite:openshift/conformance/parallel] [Suite:k8s] example build: https://prow.ci.openshift.org/view/gs/origin-ci-test/pr-logs/pull/openshift_cluster-etc[…]er-e2e-gcp-five-control-plane-replicas/1522236579484012544 you can grab any PR build in CEO https://github.com/openshift/cluster-etcd-operator/pulls and check, this is perma failing since Jan 21st. alternatively ci search: https://search.ci.openshift.org/?search=ephemeral+should+create+read-only+inline+ephemeral+volume&maxAge=168h&context=1&type=junit&name=.*five-control-plane-replicas&excludeName=&maxMatches=5&maxBytes=20971520&groupBy=job
*** Bug 1999964 has been marked as a duplicate of this bug. ***
These tests are failing because pods cannot start due to NodeAffinity requirements in the volumes. This is triggered by two events common to this job: 1. There are master nodes in all available zones, but that's not the case for worker nodes. 2. The StorageClass field volumebindingMode is set to Immediate. This can cause volumes to be provisioned in a zone where there are no worker nodes available. As a result, the pod referring to that volume will be unable to start.
Test case skipped when I checkedthe test result on May 30th as below: https://prow.ci.openshift.org/view/gs/origin-ci-test/pr-logs/pull/openshift_cluster-etcd-operator/816/pull-ci-openshift-cluster-etcd-operator-master-e2e-gcp-five-control-plane-replicas/1531161823405936640 Mark it as VERIFIED.
