After confirming that work processes can be continued no matter what state the cluster system lapses into, you can begin actual operations.
Note
The cluster system can continue work processes even if a failure occurs. However, work processes cannot be continued if another failure occurs during single node operation before the first failure is corrected. To enhance reliability, you need to eliminate the cause of the failure immediately and recover the dual node operation.
