You can perform the following operations on MRS:
- Start the service in the Stopped, Stop Failed, or Failed to Start state to use the service.
- Stop the services or stop abnormal services.
- Restart abnormal services or configure expired services to restore or enable the services.
Prerequisites
- You have synchronized IAM users. (On the Dashboard page, click Synchronize on the right side of IAM User Sync to synchronize IAM users.)
Impact on the System
- The stateful component cannot be added to the task node group.
Starting, Stopping, and Restarting a Service
- On the MRS cluster details page, click Components.
- Locate the row that contains the target service, Start, Stop, and Restart to start, stop, or restart the service.
Services are interrelated. If a service is started, stopped, and restarted, services dependent on it will be affected.
The services will be affected in the following ways:
- If a service is to be started, the lower-layer services dependent on it must be started first.
- If a service is stopped, the upper-layer services dependent on it are unavailable.
- If a service is restarted, the running upper-layer services dependent on it must be restarted.
