Final answer:
The command to enable maintenance mode on the Cluster Master is 'cluster-manage --switchMaintenanceMode active'. While in maintenance mode, some cluster features may be disabled or limited to ensure a stable environment for maintenance activities.
Step-by-step explanation:
The command to enable maintenance mode on the Cluster Master is cluster-manage --switchMaintenanceMode active. This command activates the maintenance mode on the Cluster Master and allows you to perform necessary maintenance tasks without disrupting the cluster's normal operation.
For example, if you need to update the software on the Cluster Master or perform any other configuration changes that may affect the cluster's availability, you can enable maintenance mode using this command.
While in maintenance mode, some cluster features may be temporarily disabled or limited to ensure a stable environment for maintenance activities. Once the maintenance tasks are completed, you can deactivate maintenance mode using the cluster-manage --switchMaintenanceMode inactive command.
