Updating the Cluster Configuration
Many configuration settings can be updated on a running cluster, while others require that
the nodes are relaunched to activate the changes. All settings can be edited by clicking
Action > Edit Cluster Configuration and editing the cluster
configuration file, and some, such as SSL certificates, can be edited by clicking the cluster
and going to the relevant tab.
Note: Configurations that can only be set upon initial boot
require relaunching the nodes in the cluster. Currently the administrator has to terminate
and launch new nodes manually.
Options Configurable on a Live Server
To update a running cluster, click Action > Edit Cluster Configuration to open the cluster configuration file. For a few settings, click the cluster and open the relevant tab. Once your changes are saved, Cluster Manager pushes the new configuration settings to the nodes and restarts the necessary services.| Configuration | Cluster Conf Setting | GUI |
|---|---|---|
| EIP pool | eip_pool | |
| Image ID for cluster nodes Note: Changing this setting triggers an image upgrade.

Options Configurable by Relaunching Nodes
The following options can only be set during the server boot process. To change these settings and apply them to cluster nodes, Aspera recommends editing the cluster configuration file, then terminating nodes one by one to cycle them out of the cluster. Cluster Manager relaunches the nodes with the new settings.
