Removing zombie node

A while ago I removed a node (on EC2) with decommission and removed its token. It all seemed happy at the time, but on creating a column family, I get this:

Waiting for schema agreement...
Warning: unreachable nodes <ip>... schemas agree across the cluster

The IP it lists is not in the ring. How do I rid myself of this zombie node?

Short version is, it's harmless.

A full cluster restart (all at once) would clear it out though.
