> Should StorageTool support accepting non-UUIDs via its --cluster-id argument?  One purpose of the tool is to minimize the chance that a broker could use data from the wrong volume (i.e. data from another cluster). Generating a random UUID via the --random-uuid parameter encourages using a globally unique value for every cluster and is consistent with the behavior today with ZooKeeper, whereas allowing a non-UUID here would increase the chance that someone could reuse a Cluster ID value across clusters and short-circuit the risk mitigation that this tool provides.
