Pod cannot mount volume

Hello,

I’ve just deployed a new kubernetes cluster on openstack.
pods without volume are running perfectly. But when I create a pod that uses a volume, it stuck in ContainerCreating status.

When I describe the pod, I see :

Events:

In openstack console I can see the the volume is properly created and it’s mounted to /dev/sdc.

Did I miss something ?
