ALM-12005 OKerberos Resource Abnormal

Alarm Description

The alarm module checks the status of the Kerberos resource in Manager every 80 seconds. This alarm is generated when the alarm module detects that the Kerberos resources are abnormal for six consecutive times.

This alarm is cleared when the alarm handling is complete and the Kerberos resource status recovers.

In MRS 3.3.1 and later versions, the alarm name is changed from "OKerberos Resource Abnormal" to "Manager OKerberos Resource Abnormal".

Impact on the System

The component web UI authentication services are unavailable and cannot provide security authentication functions for web upper-layer services. You may fail to log in to FusionInsight Manager and component web UIs.

Possible Causes

The OLdap resource on which OKerberos depends is abnormal.

Handling Procedure

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

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

   You can log in to the FusionInsight Manager using the floating IP address and run the sh ${BIGDATA_HOME}/om-server/om/sbin/status-oms.sh command to check the current Manager HA information.

2. Run the sh ${BIGDATA_HOME}/om-server/OMS/workspace0/ha/module/hacom/script/status_ha.sh command to check whether the status of the OLdap resource managed by HA is normal. In single-node system, the OLdap resource is in the Active_normal state. In active-standby system, 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 Step 4.
   • If no, go to Step 3.

3. Rectify the fault by following the instructions in ALM-12004 OLdap Resource Abnormal. After the OLdap resource status is recovered, check whether the OKerberos resource status is recovered.
   • If yes, no further action is required.
   • If no, go to Step 4.

Collect fault information.

4. On MRS Manager, choose O&M > Log > Download.
