Impact on the System

The component WebUI authentication services are unavailable and cannot provide security authentication functions for web upper-layer services. Users may be unable to log in to FusionInsight Manager and the WebUIs of components.

Possible Causes

The OLdap resource on which the Okerberos depends is abnormal.

Procedure

Check whether the OLdap resource on which the Okerberos depends is abnormal in the Manager.

  1. Log in the Manager node in the cluster as user omm.

    Log in to FusionInsight Manager using the floating IP address, and run the sh ${BIGDATA_HOME}/om-server/om/sbin/status-oms.sh command to check the information about the current Manager two-node cluster.

  2. Run the sh ${BIGDATA_HOME}/om-server/OMS/workspace0/ha/module/hacom/script/status_ha.sh command to check whether the OLdap resource status managed by HA is normal. (In single-node mode, the OLdap resource is in the Active_normal state; in the two-node mode, the OLdap resource is in the Active_normal state on the active node and in the Standby_normal state on the standby node.)

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

  3. See the procedure in ALM-12004 OLdap Resource Abnormal to resolve the problem. After the OLdap resource status recovers, check whether the OKerberos resource status is normal.

    • If yes, the operation is complete.
    • If no, go to 4.

Collect fault information.

  1. On the FusionInsight Manager home page, choose O&M > Log > Download.
  2. Select OmsKerberos and OmmServer from the Service and click OK.
  3. Click in the upper right corner, and set Start Date and End Date for log collection to 1 hour ahead of and after the alarm generation time, respectively. Then, click Download.
  4. Contact the O&M personnel and send the collected log information.

Alarm Clearing

After the fault is rectified, the system automatically clears this alarm.
