Enabling the Object Service on a Node

This section describes how to enable the object service for a node in a storage pool.

Prerequisites

A storage pool has been created.
This operation can be performed only when no node with the object service enabled exists in the storage pool. Otherwise, add nodes for the object service by following the instructions in Adding a Node for an Enabled Service.
The object service is supported only when Service Type is set to Intelligent video and image and a license that supports SmartInterworking is imported. The object service is not supported in IVS scenarios.
NTP synchronization must be configured for each cluster. You are advised to use the same NTP time source. For details, see Time Settings. The configuration item is Synchronize with NTP server time. Administrators are not allowed to manually adjust the time of cluster nodes. Otherwise, conflict processing may be different, causing data inconsistency.

Procedure

Choose Resources > Resources > Services > Basic Service.
Click Enable Service.
The Enable Service page is displayed.
Select the storage pool for which you want to enable the object service.
Select Add Service in Operation.

This parameter is displayed only when at least one service is enabled on the nodes in the storage pool.
Select Object in Service Type.
Based on service requirements, select at least three nodes in the Available Nodes area on the left. They will be automatically added to the Selected Nodes area on the right.

This operation is required only when all services (file, object, and HDFS services) of the storage pool are disabled. Otherwise, the system enables the object service for all nodes that have been enabled with another service.
Click OK.
The Configure Object Service page is displayed.

In the Region Configuration area, configure region information.

Select the Multiple Clusters tab and click Yes in Default Cluster.

In the Global Domain Name area, configure the domain name of the global region.
- A domain name contains 3 to 253 characters, including lowercase letters, digits, and hyphens (-). A sub-domain name cannot start or end with a hyphen (-).
- The domain name must contain a second-level domain name. Each sub-domain name contains 1 to 63 characters and is separated from each other using periods (.). The top-level domain name cannot contain digits only.
- A maximum of 128 domain names with no hierarchical relationship can be entered. Separate the domain names with semicolons (;).

In the Region Configuration area, configure region information.
