Known issues

Following are the platform-related known issues in the CDP Private Cloud Data Services 1.5.1-CHF1 hotfix release:
CDPVC-1137 and COMPX-15083: OpenShift Container Platform version upgrade from 4.10 to 4.11 fails due to a Pod Disruption Budget (PDB) issue
PDB can prevent a node from draining which makes the nodes to report the Ready,SchedulingDisabled state. As a result, the node is not updated to correct the Kubernetes version when you upgrade OCP from 4.10 to 4.11.
To resolve this issue, confirm that the upgrade has failed due to the PDB issue, and then manually delete the PDBs from the Private Cloud namespace.
  1. Run the following command to check whether the nodes are stuck in the Ready,SchedulingDisabled state:
    oc get nodes
  2. Get the machine config daemon details of the particular pod as follows:
    oc get po -n openshift-machine-config-operator -l 'k8s-app=machine-config-daemon' -o wide
  3. Check the logs of the machine config operator of that particular node as follows:
    oc logs -f -n openshift-machine-config-operator [***MACHINE-CONFIG-DAEMON-NAME***] -c machine-config-daemon

    Replace [***MACHINE-CONFIG-DAEMON-NAME***] with the actual machine config daemon name.

    You may see one of the following errors in the node logs:
    • error when evicting pods/cdp-release-cpx-liftie-****" -n "[***PRIVATE-CLOUD-NAMESPACE***] Cannot evict pod as it would violate the pod's disruption budget
    • error when evicting pods/"cdp-release-cluster-proxy-[******]" -n "[***PRIVATE-CLOUD-NAMESPACE***] Cannot evict pod as it would violate the pod's disruption budget
    Delete the PDB from the Private Cloud namespace as follows:
    1. Obtain the PDB for the cdp-release-cluster-proxy namespace:
      oc get pdb -n [***PRIVATE-CLOUD-NAMESPACE***] | grep cdp-release-cluster-proxy
    2. Back up the PDB:
      oc get pdb [***PDB-NAME-OF-CLUSTER-PROXY***] -n [***PRIVATE-CLOUD-NAMESPACE***] -o yaml >> [***BACKUP-FILE-NAME***].yaml
    3. Delete the PDB:
      oc delete pdb [***PDB-NAME-OF-CLUSTER-PROXY***] -n [***PRIVATE-CLOUD-NAMESPACE***]

    Repeat the steps to delete the cdp-release-cpx-liftie PDB as well.
