The Static Route Is lost Due to Physical Poweroff of a VM

The Static Route Is lost Due to Physical Poweroff of a VM

Symptom

After the physical server where a VM is deployed is powered off and restarted, the DHCP server fails to be started. As a result, the network script in /etc/rc.d/init.d of the faulty VM node fails to be executed, and static routes fail to be added.

After logging in to the system, you can check the system error log /var/log/message of the VM. The information in the red box in the following figure is displayed.

Run the following command to check the route:

route -n

If the command output does not contain configured static routes, which are similar to the content in the red box of the following figure, static routes configured on the node are lost.

Possible Causes

After a node is powered off and then restarted, the DHCP server fails to be started.

Troubleshooting Method

  1. Use PuTTY to log in to the faulty node as the paas user.

    Default password: QAZ2wsx@123!

    NOTE:

    In this case, you may fail to log in to the static route network segment. You can use the default route network segment or VNC to log in to the node.

  2. Run the following command to switch to the root user:

    su - root

  3. Run the following command to restart the network service:

    service network restart

  4. Run the following command to check whether the route is restored:

    route -n

    If the command output contains the configured static route, the route is restored.

  5. If the problem persists, contact technical support for assistance.
