Description of problem (please be detailed as possible and provide log snippests): Volume snapshot creation is failing on a cluster upgraded form OCS 4.6 to OCS 4.7. The OCP version is 4.6. This error is repeated in csi-snapshotter container logs. 2021-01-25T17:29:01.348176975Z I0125 17:29:01.348136 1 reflector.go:255] Listing and watching *v1.VolumeSnapshotClass from github.com/kubernetes-csi/external-snapshotter/client/v4/informers/externalversions/factory.go:117 2021-01-25T17:29:01.350299415Z E0125 17:29:01.350271 1 reflector.go:138] github.com/kubernetes-csi/external-snapshotter/client/v4/informers/externalversions/factory.go:117: Failed to watch *v1.VolumeSnapshotClass: failed to list *v1.VolumeSnapshotClass: the server could not find the requested resource (get volumesnapshotclasses.snapshot.storage.k8s.io) Build url - https://ocs4-jenkins.rhev-ci-vms.eng.rdu2.redhat.com/job/qe-deploy-ocs-cluster/16688/ All snapshot tests failed: 1.tests/manage/pv_services/pvc_snapshot/test_pvc_snapshot.py::TestPvcSnapshot::test_pvc_snapshot[CephBlockPool] 2.tests/manage/pv_services/pvc_snapshot/test_pvc_snapshot.py::TestPvcSnapshot::test_pvc_snapshot[CephFile System] 3.tests/manage/pv_services/pvc_snapshot/test_rbd_block_pvc_snapshot.py::TestRbdBlockPvcSnapshot::test_rbd_block_pvc_snapshot 4.tests/manage/pv_services/pvc_snapshot/test_restore_snapshot_using_different_sc.py::TestRestoreSnapshotUsingDifferentSc::test_snapshot_restore_using_different_sc 5.tests/manage/pv_services/pvc_snapshot/test_snapshot_at_different_pvc_utlilization_level.py::TestSnapshotAtDifferentPvcUsageLevel::test_snapshot_at_different_usage_level 6.tests/manage/pv_services/pvc_snapshot/test_snapshot_restore_with_different_access_mode.py::TestSnapshotRestoreWithDifferentAccessMode::test_snapshot_restore_with_different_access_mode logs - http://magna002.ceph.redhat.com/ocsci-jenkins/openshift-clusters/j003ai3c33-uan/j003ai3c33-uan_20210125T151654/logs/testcases_1611601132/ List of snapshots in not ready state - http://magna002.ceph.redhat.com/ocsci-jenkins/openshift-clusters/j003ai3c33-uan/j003ai3c33-uan_20210125T151654/logs/testcases_1611601132/ocs_must_gather/quay-io-rhceph-dev-ocs-must-gather-sha256-5ac742001d236e9f6a2f54db2b389990fdef04064ac7dc0ae89a7f4937c779e1/namespaces/openshift-storage/oc_output/volumesnapshot_-A Snapshot class yaml - http://magna002.ceph.redhat.com/ocsci-jenkins/openshift-clusters/j003ai3c33-uan/j003ai3c33-uan_20210125T151654/logs/testcases_1611601132/ocs_must_gather/quay-io-rhceph-dev-ocs-must-gather-sha256-5ac742001d236e9f6a2f54db2b389990fdef04064ac7dc0ae89a7f4937c779e1/namespaces/openshift-storage/oc_output/volumesnapshotclass Version of all relevant components (if applicable): $ oc get csv NAME DISPLAY VERSION REPLACES PHASE ocs-operator.v4.7.0-238.ci OpenShift Container Storage 4.7.0-238.ci ocs-operator.v4.6.1 Succeeded Cluster version is 4.6.0-0.nightly-2021-01-22-123731 Does this issue impact your ability to continue to work with the product (please explain in detail what is the user impact)? Yes Is there any workaround available to the best of your knowledge? No Rate from 1 - 5 the complexity of the scenario you performed that caused this bug (1 - very simple, 5 - very complex)? 2 Can this issue reproducible? Reporting first instance Can this issue reproduce from the UI? If this is a regression, please provide more details to justify this: Yes, the tests were passing in OCP4.6-OCS4.6 cluster. Steps to Reproduce: 1. Create CephFS and RBD PVCs. 2. Create snapshots of the PVCs OR Run the test - tests/manage/pv_services/pvc_snapshot/test_pvc_snapshot.py Actual results: PVC snapshot creation fails Expected results: PVC snapshot creation should succeeded Additional info:

I tested with OCP 4.6.0-0.nightly-2021-02-05-192240, ocs-operator.v4.7.0-250.ci. I tried creating the snapshots via the UI. Both snapshots of cephfs and rbd-based PVCs failed to be created successfully, they were stuck in Pending state with the events "Generated from snapshot-controller: Waiting for a snapshot default/cephfspvc-snapshot to be created by the CSI driver" and "Waiting for a snapshot default/rbdpvc-snapshot to be created by the CSI driver" correspondingly. Automated tests failed as well: https://ocs4-jenkins-csb-ocsqe.apps.ocp4.prod.psi.redhat.com/job/qe-deploy-ocs-cluster/295/
@Elena can you please try with latest OCS version. ocs-operator.v4.7.0-250.ci is quite old and will be having this issue. Please try with ocs-operator.4.7.0-721.ci PS: I am putting latest tag in Fixed in version field because I am not sure about the exact version where the builds started pointing to 4.6 sidecar.
