Impact on the System

  • If a single LVS node or a single Server node is faulty, the management plane can still run properly with reduced availability.
  • If two LVS nodes or two Server nodes are faulty, the management plane cannot run properly.

Possible Causes

  • The LVS node process is faulty.
  • The process on the backend management node connected to the LVS node is faulty.
  • The link between the LVS node and the back-end management node is abnormal.

Procedure

  1. Check the alarm causes and obtain the information about the node for which the alarm is generated. That is, the cause and faultNode fields in Additional Information on the alarm page.

    The serverName field contains the name and the IP address of the node for which the alarm is generated, for example, dcs-server(10.171.251.125).

  2. Log in to the LVS node and handle the alarm.

    1. Use PuTTY to separately log in to the lvs1 and lvs2 nodes as the paas user. (Obtain the IP addresses of the lvs1 and lvs2 nodes from the common stack parameters.)

    2. Log in to the lvs1 and lvs2 nodes to check whether the Keepalived process is normal.

      ps -wwf -u paas| grep keepalived | grep -v grep

      • If the process is running properly as shown in the following figure, go to 2.d.

      • If no process is displayed, go to 2.c.
    3. Run the following command to start the Keepalived process:

      /etc/keepalived/keepalived start

      • If the alarm is cleared, no further action is required.
      • If the alarm is not cleared, go to 2.d.
    4. View the /var/log/messages and /opt/dcs/logs/keepalived.log files to locate the cause of the process failure.
      • If the alarm is cleared after the alarm cause is located and the fault is rectified, no further action is required.
      • If the issue persists, contact technical support.

Alarm Clearing

If the process or link becomes normal after the fault is rectified, the system automatically clears the alarm.
