Fixed In Version: 4.7.1-403.ci
Doc Type: Bug Fix
Doc Text:
Previously, a newly restored PVC could not mount if some of the OCP nodes were running on a Red Hat Enterprise Linux version less than 8.2. Additionally, the snapshot from which it was restored is also deleted. With this update, before mounting the Red Hat Enterprise Linux nodes version less than 8.2 kernels the CephCSI flattens the RBD image if the parent RBD image is not present in the pool.

Comment 7 Jilju Joy 2021-05-31 18:27:53 UTC 
Verified by the test case tests/manage/pv_services/pvc_snapshot/test_snapshot_at_different_pvc_utlilization_level.py::TestSnapshotAtDifferentPvcUsageLevel::test_snapshot_at_different_usage_level.
The test case deletes snapshot and parent PVC before attaching the restored RBD PVC to the pod.

Test case logs : http://magna002.ceph.redhat.com/ocsci-jenkins/openshift-clusters/jijoy-may31/jijoy-may31_20210531T142523/logs/ocs-ci-logs-1622479448/tests/manage/pv_services/pvc_snapshot/test_snapshot_at_different_pvc_utlilization_level.py/TestSnapshotAtDifferentPvcUsageLevel/test_snapshot_at_different_usage_level/logs

Worker nodes kernel version is 3.10.0-1160.25.1.el7.x86_64
