Hello, friend!

The possible cause is the LdapServer process in the Manager is abnormal.

You can refer to the following steps to solve the alarm.

Check whether the LdapServer process in the manager is normal.

1. Log in to 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 ps -ef | grep slapd command to check whether the LdapServer resource process in the ${BIGDATA_HOME}/om-server/om/ in the process configuration file is running properly.

NOTE

You can determine that the resource is normal by checking the following information:

a. After the sh ${BIGDATA_HOME}/om-server/om/sbin/status-oms.sh command runs, ResHAStatus of the OLdap is Normal.

b. After the ps -ef | grep slapd command runs, the slapd process of port 21750 can be viewed.

  • If yes, go to Step 3.

  • If no, go to Step 4.

3. Run the kill -2 ldap pid command to restart the LdapServer process and wait for 20 seconds. The HA starts the oldap process automatically. Check whether the current OLdap resource is in normal state.

  • If yes, the operation is complete.

  • If no, go to Step 4.

Collect fault information.

4. On the FusionInsight Manager home page, choose O&M > Log > Download.

5. Select OmsLdapServer and OmmServer from the Service.

6. Click changein 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.

7. Contact the technical support and send the collected log information.

Hope this helps!

Hello, Jackson!

The system checks LDAP resources every 60 seconds. This alarm is generated whenthe system detects that the LDAP resources in Manager are abnormal for six consecutive times.

This alarm is cleared when the Ldap resource in the Manager recovers and thealarm handling is complete.

Impact on the System

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

Thanks!
