Extra configuration
Management HA configuration
If you have more than three nodes in the cluster, you can enable high availability (HA) of the management node. To do this, you need to define extra public and internal addresses for HA purposes.
1. Go to Settings > System settings > Management node high availability and click Create HA configuration.
2. Select three nodes to be used in the HA configuration and click Next.
3. Specify one public and one internal addresses to be used as virtual addresses for HA:
- 192.168.XX.250
- 172.16.XX.250
If one of the three nodes fails, you can still have connectivity and access to the cluster using these virtual addresses.
4. Click Create.
More detailed information about the progress can be checked in the /var/log/vstorage-ui-backend/ansible.log log file.
This operation assigns the IP address “250” as the HA main IP address and the admin panel access. Now, you can open a new browser tab and enter the URL https://172.16.XX.250:8888.
You can check the status of the HA configuration in the command-line interface by running:

5. Add the remaining nodes to the compute cluster.
