The upgrade cluster operation committed successfully with the Version Control Manager. However, a fault has occured during the subsequent group transition that coordinates the upgrade of all other metadata server components and GS itself.
View the server logs to determine the cause of the fault. The upgradecluster command has committed with the Version Control Manager, so the next successful group transition will complete the upgrade automatically, and there is no need to re-issue the upgradecluster command.
