This error message indicates that the Kubernetes scheduler was unable to schedule a pod on any of the available nodes in the cluster.
The first node had an untolerated taint of “node.kubernetes.io/unreachable,” meaning it was marked as unavailable for scheduling due to some issue with connectivity or availability.
The second node had a volume node affinity conflict, which means that the pod’s requirements for accessing specific volumes or storage were not compatible with the nodes that were available.
In this case, preemption (the process of evicting lower-priority pods to make room for higher-priority ones) would not be helpful for scheduling because there were no other available nodes that met the pod’s requirements.
To resolve this issue, you may need to investigate and address the underlying causes of the taint and volume affinity conflicts on your nodes, or consider adjusting your pod’s resource requests or tolerations to make it more compatible with the available resources in your cluster.
