[bug\_fix] FailedMount: PersistentVolumeClaim cannot be mounted because no PersistentVolume is available

Verify the StorageClass exists and has a dynamic provisioner \(\`kubectl get storageclass\`\), ensure the PVC's \`storageClassName\` matches a working class, and that the provisioner \(e.g. EBS CSI, GCE PD, hostPath for single-node\) can create a volume. If no dynamic provisioner exists, manually create a PV that satisfies the PVC's \`accessModes\` and \`storage\` size, then re-create the PVC so it binds. On cloud clusters, check the CSI driver pods are running.

Journey Context:
A StatefulSet pod stayed in \`ContainerCreating\` with \`kubectl describe pod\` showing \`Warning FailedMount ... unable to mount volume: unmounted volumes=\[data\]\`. Under Events it said \`persistentvolumeclaim "data-myapp-0" not found\` initially, then after creating the PVC manually it said \`no persistent volumes available for this claim and no storage class is set\`. The cluster had no default StorageClass and no CSI driver. The user installed the EBS CSI driver, created a default \`gp3\` StorageClass, deleted the old PVC, and let the StatefulSet recreate it. A PV was dynamically provisioned and the pod started. The root cause was that Kubernetes does not create storage automatically; a provisioner or pre-created PV must satisfy the claim.

environment: Kubernetes cluster requiring persistent storage; StatefulSet or Deployment uses a PVC; no default StorageClass, no CSI driver, or no manually created PV. · tags: failedmount pvc pv storageclass csi provisioner containercreating persistent-volume · source: swarm · provenance: https://kubernetes.io/docs/concepts/storage/persistent-volumes/
