Impact on the System

Manager active/standby switchover may occur. The Manager and WebUI authentication service of components is unavailable. Security authentication and user management functions cannot be provided for upper-layer web services. As a result, you may fail to log in to the Manager and WebUI of components.

Possible Causes

The LdapServer process in the Manager is abnormal.

Handling Procedure

Check whether the LdapServer process in the Manager is normal.

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 ${BIGDATA_HOME}/om-server/om/sbin/status-oms.sh command to check the information about the current Manager two-node cluster.
Run ps -ef | grep slapdcommand to check whether the LdapServer resource process in the${BIGDATA_HOME}/om-server/om/ in the process configuration file is running properly.
You can determine that the resource is normal by checking the following information:
1. After the sh ${BIGDATA_HOME}/om-server/om/sbin/status-oms.shcommand runs,ResHAStatusof the OLdap isNormal.
2. After the ps -ef | grep slapd command runs, the slapd process of port 21750 can be viewed.
  - If yes, go to 3.
  - If no, go to 4.
Run the kill -2ldap 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 4.
