The Cassandra pod will get scheduled to run on a different worker node, provided there is an available node that satisfies affinity rules, resource requirements, etc. And you are correct that the volume will get remounted. If however you are using a local or hostPath volume, then it will be lost and you will want to restart Cassandra with the -Dcassandra.replace_address option.
