The <none> indicator is not an issue -- it simply indicates that those nodes are worker nodes and don't have stateful information stored on them.
Hanging engines on "ContainerCreating" typically means you have not run "cdsw enable <worker-ip>" on the master node for all your worker nodes. This whitelists the IP of your worker nodes for NFS mounts. If you have not done this, containers can hang waiting for the project mounts to become available when scheduled onto a worker node.
Please let me know if running "cdsw enable" for each worker IP resolves this issue.
FYI, i was having the same issue. and this resolved it for me.
