CubeCOS Startup

Single Node Startup

Perform Node Configuration on Single Node

CubeCOS automatically bootstraps cluster services upon startup. The steps below outline the bootstrapping process and how to monitoring status for single node deployments.

1. Powering on a single node.

   Power up the machine hosting the single deployed nodes.

2. Single node initiating bootstrap modules.

   Bootstrapping will be handled automatically. While bootstrapping, the console displays a services n/a message.

   

3. Check and repair services.

   While bootstrapping, CubeCOS automatically checks and repairs services. Wait until all services are ready. Services are considered ready when the console displays the Service Ready message.

   

4. Cluster ready.

   Press F2 to enter the console, login as admin and run cluster check to verify that all services are ok.

Cluster Startup

Perform Node Configuration on Cluster

CubeCOS automatically bootstraps cluster services upon a cluster start up. Cluster setup behavior applies to AIO, HCI and web scale deployments.

The steps below outline the bootstrapping process and how to monitoring status for cluster deployments.

1. Power on all nodes.

   Power up all cluster machines.

2. Wait for the master node to initilize.

   The master node will begin the bootstrapping process, while all other nodes wait until it completes.

   

3. Monitoring the bootstrap process.

   You can monitor the bootstrap process from the console of other nodes. While waiting for the master to finish bootstrapping, the console displays Waiting for master control to finish bootstrap_cube [x min].

   

4. Cluster initialization after master bootstrap

   info

   For configurations with converged control nodes (AIO, Single node), the startup initiates and complete on the master node fisrt, Next, all nodes will join the cluster.

   For configurations with dedicated control nodes (HCI, Web Scale), the startup initiates and completes on the master node first. Next, the two control nodes join the cluster, and finally, all remaining nodes join the cluster.

   After the master node finishes bootstrapping and displays a Starting cluster message, all child nodes proceed to join the cluster.

   

   Other nodes will begin their bootstrapping process and join the cluster.

   

5. Cluster services check and repair after bootstrap.

   CubeCOS automatically perform services check and repair as the last step of cluster bootstrap. The service check and repair ensures all modules have properly started and no warnings or error occurred during startup. Wait until services to become ready and the console displays cluster checked and repaired.

   

6. Verify cluster service and check results.

   After the clsuter services check and repair. Verify that servies ready is displayed on the node consoles.

   To verify service status, press F2 to open the console, log in with the admin account, and run the cluster check command. Ensure all services return an ok status.
