Issue/Introduction

In the vCenter console, the  Aria Operations for logs VM displayed the following error: "NO NETWORK DETECTED. PLEASE CHECK THE NETWORK CONFIGURATION."

 

 

 

Environment

VMware Aria Operations for logs 8.18.x

Cause

A configuration corruption occurred within the /etc/systemd/network/10-eth0.network file where the required [Match] keyword was missing, preventing the systemd-networkd service from correctly identifying and configuring the network interface.

Resolution

Follow the steps below to resolve the issue

1. Log in to the affected node console (via vCenter Remote Console).

2. Navigate to the network configuration directory: cd /etc/systemd/network/

3. Open the configuration file for editing: vi 10-eth0.network

4. Verify/Add the [Match] Section: Ensure the file starts with the [Match] keyword.
5. A standard working configuration should look like this:
    

[Match]
Name=eth0

[Network]
Address=<NODE_IP>/<CIDR>
Gateway=<GATEWAY_IP>
DNS=<DNS_IP>

6.Save and exit (:wq).

7.Apply Changes and Verify 

• • Restart the network daemon to apply the fix: systemctl restart systemd-networkd

  • Verify the interface has an IP: ip addr show eth0

  • Restart the Log Insight service: service loginsight restart

  • Check the Cluster UI on the Primary node to confirm the worker node status returns to Connected.
