Parameters

Name

Meaning

Source

Specifies the cluster for which the alarm is generated.

ServiceName

Specifies the service for which the alarm is generated.

RoleName

Specifies the role for which the alarm is generated.

HostName

Specifies the host for which the alarm is generated.

Impact on the System

In storage-compute decoupling scenarios, the cluster cannot obtain the latest temporary AK/SK, which may lead to failure access to OBS.

Possible Causes

  • The meta role of the MRS cluster is abnormal.
  • The cluster has been bound to an agency and accessed OBS but has been unbound from the agency. As a result, the cluster has not been bound to any agency.

Procedure

Check the status of the meta role.

  1. On FusionInsight Manager of the cluster, choose O&M > Alarm > Alarms. On the page that is displayed, click in the row containing the alarm, and determine the IP address of the host for which the alarm is generated.
  2. On FusionInsight Manager of the cluster, choose Cluster > Services > Meta. On the page that is displayed, click the Instance tab, and check whether the meta role corresponding to the host for which the alarm is generated is normal.

    • If yes, go to 4.
    • If no, go to 3.

  3. Select the abnormal role and choose More > Restart Instance to restart the abnormal meta role. After the restart is complete, check whether the alarm is cleared several minutes later.

    • If yes, no further action is required.
    • If no, go to 4.

Rebind the cluster to an agency.

  1. Log in to the MRS management console.
  2. In the navigation pane on the left, choose Clusters > Active Clusters. On the page that is displayed, click the cluster name to go to its overview page. Then, check whether the cluster is bound to an agency in the O&M management area.

    • If yes, go to 7.
    • If no, go to 6.

  3. Click Manage Agency. On the page that is displayed, rebind the cluster to an agency. Then check whether the alarm is cleared a few minutes later.

    • If yes, no further action is required.
    • If no, go to 7.

  4. Contact O&M personnel.
