Worth noting that repair may not work, as it’s possible that NONE of the nodes with data (for some given row) are no longer valid replicas according to the DHT/Tokens, so repair will not find any of the replicas with the data.

Yep. https://issues.apache.org/jira/browse/CASSANDRA-7069 - "Prevent operator mistakes due to simultaneous bootstrap" But this doesn't handle your case, where you force joined a bunch of nodes with auto_bootstrap=false. Probably if I were in your case (and realized it immediately) I would decommission all nodes and then start again. I probably would not run repair, though that would also work. I agree with jeffj down-thread that you should not run cleanup. =Rob
