Possible Causes

The Keepalived heartbeat between two LVS nodes is interrupted, but the arbitration center cannot detect heartbeat interruption.

Procedure

Perform the following operations to handle this issue:

  1. Log in to the alarm system and query alarm information.
  2. Run the following command and enter the root password QAZ2wsx@123! to switch to the root user:

    su - root

  3. Use PuTTY to log in to the LVS node and check the status of the current LVS node.

    Run the following command:

    cat /opt/dms/lvs/jobs/lvs/status_dir/status

    Check whether statuses of both nodes are master.

    • If they are, go to 4.
    • If status of one LVS node is master and that of the other is backup, the network is restored and the alarm is cleared.

  4. Run the ping command to check whether the two nodes are connected.

    • If the communication between the two nodes is abnormal, rectify the fault.
    • If the communication is normal but the fault persists, contact technical support.

Alarm Clearing

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