I get the sense you mean that you dropped the OpsCenter keyspace. If you're still monitoring the cluster with OpsCenter, the keyspace will get recreated.

Please log a ticket with DataStax Support so one of our engineers can assist you. Cheers!

It sounds like you have a schema disagreement and the schema change didn't get propagated to all nodes.

As I previously stated, this Q&A forum isn't intended as a replacement for support. You will need to log a ticket for support issues so our team of engineers can assist you. Cheers!
