Trouble configuring JupyterHub with Kubernetes on my local cluster

JupyterHub Zero to JupyterHub on Kubernetes
1

Hello,
I succeeded in deploying a Kubernetes on my on-premises 3-master 3-worker cluster.
I failed in configuring the Persistent Volumes. It leads to a jupyterhub pod remaining “pending”.
The error message included in the pod description is:0/6 nodes are available: 1 node(s) had taint {node.kubernetes.io/unreachable: }, that the pod didn't tolerate, 5 node(s) didn't find available persistent volumes to bind.
I join my PersistentVolume and PersistentVolumeClaim configurations hereafter.
The pv, pvc and sc are ok on every node.
Thanks for any help

@hdlbq0 I’ve editted your post so that your configuration is formatted. For future reference if you want to format a multi-line code block you can use triple backticks
