Checking the GaussDB(DWS) Cluster Status

Choose Dedicated Clusters > Clusters and you can view the general information about a cluster in the displayed cluster list, such as the cluster status, task information, recent events, and node specifications.

Querying General Information of a Cluster

Log in to the GaussDB(DWS) console. In the navigation pane, choose Dedicated Clusters > Clusters. The cluster list displays all clusters. If there are a large number of clusters, you can turn pages to view the clusters in any status.

In the upper part of the cluster list, click the search box and search for the required cluster based on the filter criteria (cluster name, cluster status, cluster version, task information, node specifications, recent events, and enterprise project). Click to refresh the cluster list. You can also click Search by Tag to search for clusters based on cluster tags. For details, see Searching for Clusters Based on Tags.

Clusters are listed in chronological order by default, with the most recent clusters displayed at the top. Table 1 describes the cluster list parameters.

Table 1 Cluster list parameters
Parameter	Description
Cluster Name	Cluster name specified when a cluster is created. NOTE: If the cluster name cannot be changed on the console, contact technical support.
Cluster Status	Cluster running status. For details, see Cluster Status.
Cluster Version	Version of the current cluster. For details, see Table 3.
Task Information	Cluster task status. For details, see Cluster Task Information.
Node Flavor	Node flavors of clusters.
Recent Events	Number of recent events in a cluster. You can click the number to view event details.
Enterprise Project	Enterprise project to which a cluster belongs.
Operation	More Convert to Encryption Cluster: For details, see Converting an Ordinary Cluster to an Encrypted Cluster. View Metric: For details, see Viewing GaussDB(DWS) Cluster Monitoring Information on Cloud Eye. Restart: Click Restart to restart a cluster. For details, see Restarting a cluster. Start: Click Start to start a stopped cluster. For details, see Starting a Cluster. Stop: Click Stop to stop a running cluster. For details, see Stopping a Cluster. Scale Node: For details, see Scaling GaussDB(DWS) Cluster Nodes. Change Specifications: For details, see Changing GaussDB(DWS) Cluster Specifications. Reset Password: For details, see Resetting the Password the GaussDB(DWS) Database Administrator. Create Snapshot: For details, see Backing Up and Restoring a GaussDB(DWS) Cluster. Delete: Click Delete to delete a cluster. Manage CN: For details, see Adding or Deleting a CN in a GaussDB(DWS) Cluster. NOTE: The positions of the function keys in the Operation column are dynamic. To ensure that there are always two function keys visible before More, any function keys that typically appear only when you hover over More will be moved to a position directly before More. This adjustment occurs if there are some functions whose keys are supposed to be placed before More but are not supported for the current site.

Cluster Status

VACUUM FULL;

Cluster Version

Table 3 Cluster version
Version	Description
x.x.x	Current cluster version. To improve system stability, click Upgradable to go to the upgrade management page. For details, see Upgrading a GaussDB(DWS) Cluster.

Cluster Task Information

Table 4 Task information description
Status	Description
Creating snapshot	Indicates that a snapshot is being created in the cluster.
Snapshot creation failed	Indicates that a snapshot fails to be created.
Observing	Indicates that the cluster is to be submitted after the automatic upgrade.
Configuring	Indicates that the system is storing modifications of cluster parameters.
Restarting	Indicates that a cluster is being restarted.
Restart failed	Indicates that a cluster fails to be restarted.
Converting to encryption cluster	Indicates that the cluster is being converted to an encrypted cluster.
Encryption cluster conversion failed	Indicates that the cluster fails to be encrypted.
Scaling out	Indicates that a cluster is being scaled out.
Scale-out failed	Indicates that a cluster fails to be scaled out.
Expanding disk capacity	Indicates that disk capacity is being expanded.
Disk expansion failed	Indicates that disk capacity fails to be expanded.
Associating ELB	Indicates that ELB is being associated.
Failed to associate ELB	Indicates that ELB fails to be associated.
Disassociating ELB	Indicates that ELB is being disassociated.
Failed to disassociate ELB	Indicates that ELB fails to be disassociated.
Checking scale-in	The service is checking whether a cluster can be scaled in.
Scale-in check failed	A cluster does not meet the scale-in requirements. For example: The value of default_storage_nodegroup is not installation. In the cluster database, data_redis is a reserved redistribution schema, but the schema contains user tables. The cluster disk space does not meet the scale-in requirements. For details, see Scaling In a Cluster.
Scaling in	A cluster is being scaled in.
Scale-in failed	The cluster scale-in fails. You need to manually scale in the cluster again as soon as possible, or your services will be affected.
Switching back	The primary/standby relationship of a cluster is being restored.
Switchback failed	The primary/standby relationship of a cluster fails to be restored. Possible causes are as follows. Redo operations are being performed on DNs. Wait until the operations are completed and try again. Failed to query DN redo information. Check tenant logs to identify the failure cause. Primary/standby catchup is in progress. Wait until it is completed and try again. Failed to query primary/standby catchup information. Check tenant logs to identify the failure cause. Primary/standby catchup failed. Contact technical support or try again later. Check tenant logs to identify the failure cause. The cluster is abnormal.
Changing node flavor	The cluster is being scaled.
Node flavor change failed	All specifications change failed
Maintaining	A maintenance change operation, such as cluster upgrade or plug-in upgrade, is being performed on the cluster.
Maintain_failure	A cluster fails to be restarted.
Stopping	Indicates that the cluster is being stopped.
Starting	Indicates that the cluster is being started.
Inspecting	Indicates that the cluster is being inspected before the change.
Inspection failed	Indicates that the cluster inspection fails.
