Register information about compute nodes.

The maximum number of registered compute nodes is 1,024 per protection domain. This maximum does not change even if storage nodes are added or removed.

  • Required role: Storage

  • When registering compute nodes to a VPS: Scope of the VPS

  1. When registering a compute node to a VPS, verify the registration-target VPS ID and conditions set for the VPS (upper limit for the number of compute nodes).

    If you want to specify a VPS by its name in the CLI, verify the VPS name.

    REST API: GET /v1/objects/virtual-private-storages

    CLI: vps_list

  2. Register information about compute nodes.

    Run either of the following commands with the nicknames of the intended compute nodes and the type of the OS running on the compute nodes specified.

    Conventions to be followed when setting a nickname

    • Number of characters: 1 to 229

    • Characters that can be used: Numbers (0 to 9), uppercase alphabet (A to Z), lowercase alphabet (a to z), symbols (\ . : @ _) for the first character. In addition to these, a hyphen (-) can be used for the second and subsequent characters.

    • Each compute node must have a unique nickname.

    REST API: POST /v1/objects/servers

    CLI: server_create

    Verify the job ID which is displayed after the command is run.

  3. Verify the state of the job.

    Run either of the following commands with the job ID specified.

    REST API: GET /v1/objects/jobs/<jobID>

    CLI: job_show

    If the job state is "Succeeded", the job is completed.

  4. Obtain a list of compute nodes and verify that the information about the intended compute nodes is registered.

    REST API: GET /v1/objects/servers

    CLI: server_list

  5. (Bare metal) Back up the configuration information.

    Perform this step by referring to Backing up the configuration information (Bare metal).

    If you continue operations with other procedures, you must back up the configuration information after you have completed all operations.
