Checking the Running Status of an MRS Cluster

Checking the Running Status of an MRS Cluster

1. Log in to the MRS console.
2. Click Active Clusters.

   By default, clusters in the cluster list are sorted by creation time. For details about the cluster list parameters, see Table 1.

   • Active Clusters: contain all clusters except the clusters in the Failed and Deleted states.
   • Cluster History: contains the clusters in the Deleted states. Only clusters deleted within the last six months are displayed. If you want to view clusters deleted six months ago, contact Huawei Cloud technical support.
   • Failed Tasks: Click to view the failed cluster creation tasks.

   Table 1 Parameters in the active cluster list

   Parameter	Description
   Name/ID	Cluster name, which is set when a cluster is created. Unique identifier of a cluster, which is automatically assigned when a cluster is created. : Change the cluster name. : Copy the cluster ID.
   Cluster Version	Cluster version.
   Cluster Type	The type of a cluster you want to create.
   Nodes	Number of nodes that can be deployed in a cluster. This parameter is set when a cluster is created.
   Status	Cluster running state and state change information. For details, see Table 2. The cluster creation progress includes: Verifying cluster parameters Applying for cluster resources Creating VMs Initializing VMs Installing MRS Manager Deploying the cluster Cluster installation failed The cluster scale-out progress includes: Preparing for scale-out Creating VMs Initializing VMs Adding nodes to the cluster Scale-out failed The cluster scale-in progress includes: Preparing for scale-in Decommissioning instance Deleting VMs Deleting nodes from the cluster Scale-in failed The system will display causes of cluster installation, scale-out, and scale-in failures. For details, see Table 6.
   Billing Mode	Currently, the commercial version of MRS is charged based on ECSs in a cluster. Yearly/Monthly: The duration ranges from one month to one year. The minimum cluster duration is 1 month and the maximum available cluster duration is 1 year. Pay-per-use: Nodes are charged by actual duration of use, with a billing cycle of one hour. The billing start time, that is, the time when the cluster node is successfully created is displayed under Billing Mode.
   Created	The time when a cluster node is successfully created. This parameter is displayed only on the Cluster History page.
   Deleted	Time when a cluster node billing stops and the cluster node begins to be deleted. This parameter is valid only for historical clusters displayed on the Cluster History page.
   AZ	Availability zone (AZ) in the region of a cluster, which is set when a cluster is created.
   Enterprise Project	Enterprise project to which a cluster belongs.

   Table 2 MRS cluster running state

   Status	Description
   Starting	When a cluster is being created, it is in the Starting state.
   Running	If a cluster is created successfully and functioning properly, it is in the Running state.
   Scaling out	If the Master, Core, or Task node in a cluster is being added, the cluster is in the Scaling out state.
   Scaling in	If a cluster node is being deleted, the cluster node is in the Scaling in state. This state shows when you scale in or elastically scale in a cluster node, decommission a node in a yearly/monthly cluster, change the OS, or reinstall the OS.
   Abnormal	If some components in a cluster are abnormal, the cluster is in the Abnormal state.
   Deleting	When you delete a pay-per-use cluster node, the cluster state changes to Deleting. This state is shown after you click Delete and confirm the deletion.
   Frozen	If the grace period of a yearly/monthly resource expires but the resource is not renewed, or if the fee of a pay-per-use resource fails to be deducted and you have not topped up your account before the grace period expires, the system freezes the resource in the Frozen state. NOTE: A frozen cluster is unavailable and its all ECSs are shut down. After being unfrozen, the cluster returns to the Running state. If no renewal fee is paid, the cluster will be deleted after a specified period (called freeze period) and the cluster status will be changed to Deleted.
   Restoring node...	If a faulty node in the cluster is being recovered, its state is Restoring node....
