kubernetes statefulset persistent-volumes yaml

I'm working on a personal project and I've spent hours debugging this and I need help solving I'm relatively new to this, so bear with me....... I'm running a StatefulSet on Kubernetes v1.24.0 for a database application that uses persistent volumes. I noticed that when one of the pods crashes, it doesn't restart properly, and I'm left with an behavior state. The pod's status shows `CrashLoopBackOff`, and when I check the logs, I see the following behavior message: ``` behavior: unable to attach or mount volumes: unmounted volumes=[data], unattached volumes=[data default-token-2k4sh] ``` I have defined my StatefulSet like this: ```yaml apiVersion: apps/v1 kind: StatefulSet metadata: name: my-database spec: serviceName: "my-database" replicas: 3 selector: matchLabels: app: my-database template: metadata: labels: app: my-database spec: containers: - name: db-container image: my-database-image:latest ports: - containerPort: 5432 volumeMounts: - name: data mountPath: /var/lib/postgresql/data volumes: - name: data persistentVolumeClaim: claimName: data-pvc volumeClaimTemplates: - metadata: name: data-pvc spec: accessModes: - ReadWriteOnce resources: requests: storage: 10Gi ``` I’ve already verified that the Persistent Volume (PV) is available and not in use by another pod. Additionally, I checked the Persistent Volume Claim (PVC), and it shows `Bound` status. However, the pod still fails to restart. I’ve tried deleting the pod manually and letting Kubernetes recreate it, but it still ends up in the same state. What could be causing this scenario, and how can I fix it so that my StatefulSet pods can recover from crashes correctly? Am I missing something obvious? How would you solve this? I'm working on a mobile app that needs to handle this. Is there a simpler solution I'm overlooking? Has anyone else encountered this?
