Description of problem:

After CSI migration tests finish, there are some leftover PVs in the cluster.

See https://testgrid.k8s.io/redhat-openshift-ocp-release-4.8-broken#periodic-ci-openshift-release-master-nightly-4.8-e2e-aws-csi-migration

ERROR: Timed out waiting for PVs to get deleted.
ERROR: It seems that some test left some PVs behind.
ERROR: Check the diff between expected and existing PVs above.

So we have three PVs left behind and not deleted. Two of them are local, the third one looks like mock:

    name: pvc-f9c9f7d0-51b8-402a-80f8-4bbc1982a6d0

How reproducible:
Always

Steps to Reproduce:
Run openshift conformance/parallel tests against OCP on AWS.

CSI migration is enabled in the linked CI jobs, IMO it should not affect local or mock volumes, but one never knows. We do not check for leftover PVs in other e2e jobs, so we don't know if there are some on GCE or without migration.

Actual results:
At least two local PVs left behind (this is 100% reproducible)

Sometimes, a CSI mock PV left behind (started appearing in https://prow.ci.openshift.org/view/gs/origin-ci-test/logs/periodic-ci-openshift-release-master-nightly-4.8-e2e-aws-csi-migration/1391332579759624192 ???)

Expected results:
No PVs left behind

The local volumes will be fixed with bug #1959445

--- Additional comment from Tomas Smetana on 2021-09-09 15:05:08 CEST ---

This is fixed in 4.9 with rebase to k8s 1.22:

Comment 4 Tomas Smetana 2022-08-19 10:05:26 UTC
Closing the bug: I'm not sure this is worth backporting. If whoever believes this should be really fixed in 4.8.z, please file a new bug in Jira: https://issues.redhat.com/secure/CreateIssueDetails!init.jspa?pid=12332330&issuetype=1
