The divingbell pods use a hostPath volume for the root filesystem.
Because this mount includes /var/lib/kubelet, the pod holds a reference
to every volume mounted by every pod on the same host.
The most visible case where this causes a problem is the termination of
a pod that uses a ceph-backed PVCs. When kubelet tries to unmap the rbd
device, it is unable to do so, manifesting in the kubelet logs as:
rbd: unmap failed: (16) Device or resource busy
This change sets the mountPropagation to HostToContainer for the rootfs
volume, so that the divingbell pods will not prevent kubelet from
releasing these devices.
