When the same host is used for a single host or cluster test, the storaged service cannot start normally. The listening port of the storaged service is red in the console.
Check the logs of the storaged service. If you find the “wrong cluster” error message, the possible cause is that the cluster id generated by Nebula Graph during the single host test and the cluster test are inconsistent. You need to delete the cluster.id file and the data directory and restart the service.
