timeout expired waiting for volumes to attach or mount for pod
It looks like your deployment has progressed successfully! The error you see occurred 2m46s from the time that you did the describe. This could be due to ceph provisioning the PV/PVC, or some other situation in which your PVC is not ready to be mounted. However, according to the events, your container eventually successfully mounts and is started. All the pod health checks pass and the Kube scheduler progresses it into the READY state.
Is there any evidence that your container and the mount is not working properly after start?
