BMYPC6002

A MachineConfigPool is degraded.

Severity

Error

Problem description

It indicates that a MachineConfigPool is in a degraded state in the OpenShift® cluster. It can impact the upgrade because the different IBM Fusion component upgrades also start machine configuration roll outs and they might not succeed if MachineConfigPool is in a degraded state. A new machine configuration must be rolled out when all MachineConfigPool are healthy.

User actions

Do the following steps to resolve the issue:
  1. The issue might occur for a short duration whenever the Machine config rollout, OpenShift Container Platform, and Global Data Platform operations are in progress. Wait for these operations to complete, then check that the MachineConfigPool is healthy and available.
  2. If a MachineConfigPool remains in a degraded state for a long time, then use following command to find the root cause.
    oc describe machineconfigpool <poolname>
  3. Check for the problems indicated in the description, and debug further to identify the root cause. The following are some possible reasons:
    • A node is stuck in a NotReady state, then restart the node to fix the issue.
    • Though the node completes the roll out, it might not be in a schedulable state. Compare the required and current configurations. If the configurations are the same, manually remove taint of the unscheduleable.
  4. After the MachineConfigPool is available and up to date, the upgrade precheck detects the fix and resumes upgrade automatically.
