I'm using RBD client to communicate ceph with kubernetes. I had created PVC 'myclaim', it is in Pending state from long time. I'm getting the below exception. I guess it may occur due to it may trying to attempt to map rbd image from ceph jewel or may be not getting keyring. Please have a look on below exception and provide proper suggestion. And if anyone having idea "How to create persistentvolume-controller either by external provisioner "ceph.com/rbd" or manually", please share your views.

Exception:
