I love RancherOS on Bare-Metal and had to add a new machine to an RKE cluster, rke up went well after adding the new machine to rancher-rke.yaml, but the new node is not ready:

k get nodes
NAME      STATUS     ROLES               AGE       VERSION
csky05    Ready      controlplane,etcd   24d       v1.12.4
csky06    Ready      worker              24d       v1.12.4
csky07    Ready      worker              24d       v1.12.4
csky08    Ready      worker              24d       v1.12.4
csky09    Ready      worker              24d       v1.12.4
csky10    NotReady   worker              6m28s     v1.12.4

any ideas?
