This error message indicates that a pod is unable to be scheduled because it has PersistentVolumeClaims (PVCs) that cannot be fulfilled by any available persistent volumes. Additionally, there are no other pods running on the nodes that can be preempted to make room for this pod.
To resolve this issue, you can try the following:
- Check if there are any unused or unclaimed persistent volumes in your cluster and create new PVCs to use them.
- Increase the size of your existing persistent volumes or add new ones to your cluster.
- Consider using dynamic provisioning with a storage class so that new PVs are automatically created when needed.
- If none of these options work, you may need to manually evict some pods from your nodes to free up resources for the pending pod.
It’s important to note that preemption is a feature in Kubernetes that allows lower-priority pods to be terminated in order to make room for higher-priority ones. However, if there are no lower-priority pods available, preemption cannot occur and the pending pod will remain unscheduled until resources become available.
