* Mounting NFS exports as volumes from some NFS servers fails because the kubelet isn't starting rpc-statd as expected. Describing pods that are stuck creating shows rpc.statd is required for remote locking * Starting rpc-statd.service resolves the issue and all NFS mounts seem to be working. * Recommended approach https://github.com/coreos/bugs/issues/2074
