DX Object Storage Platform: Advanced Node Configuration

Note: All configuration files contain name/value pairs for setting configuration options. The format

of the name/value pair lines is Name = value. Any white spaces within the name/value pair are

ignored. Blank lines and lines beginning with # are ignored. All fields are case-sensitive.

After updating all SN configuration files to assign sub-cluster membership, restarting the Storage Nodes

via the DX Storage Admin Console is required in order for the sub-cluster membership to take effect.

Once the cluster restart is complete, the DX Storage Admin Console displays the defined sub-clusters

and the Storage Nodes that have membership to those sub-clusters.

Figure 2: DX Storage Admin Console

When adding new Storage Nodes to a cluster with sub-clusters configured, it is important that the

administrator assign sub-cluster membership to the new Storage Node by updating its configuration

file. If the SN is allowed to network boot prior to the configuration file being modified, the Storage

Node will need to be restarted to pick up the sub-cluster membership information.

If sub-clusters are defined for a DX Storage cluster, any Storage Node that joins the cluster that does

not have a sub-cluster membership defined in its configuration file is automatically assigned to a

„default‟ sub-cluster. In other words, if a new Storage Node is added to a cluster where sub-clusters

are configured and the administrator fails to update its configuration file to assign it to a defined sub-

cluster, the new node will be added to the default cluster.
