### Which jobs are flaking?

master-blocking:
- gce-cos-master-default

### Which tests are flaking?

1. `Kubernetes e2e suite.[It] [sig-storage] CSI Mock volume fsgroup policies CSI FSGroupPolicy Update [LinuxOnly] should update fsGroup if update from File to default.`

2. `Kubernetes e2e suite.[It] [sig-network] Networking Granular Checks: Services should update endpoints: http`

### Since when has it been flaking?

This test is only failed **once** recently on 31/05/2024
- https://prow.k8s.io/view/gs/kubernetes-jenkins/logs/ci-kubernetes-e2e-ubuntu-gce-containerd/1796412325301850112

### Testgrid link

### Reason for failure (if possible)

**02 test seem failed with the same reason related to containerd socket.**

```

```
Related to behavior of CSI Mock volumes when updating FSGroup policies. Seems like storage issue (?)
