Adding nodes to object storage

You can add more S3 nodes for high availability and scalability of your object storage.

Prerequisites

The S3 cluster is created, as described in Creating the S3 cluster.

To add nodes to the S3 cluster

Admin panel

Go to the Storage services > S3 > Nodes screen.
Click Add node.
Select nodes to join the S3 cluster, and then click Add.

The nodes will be added to your object storage.

Command-line interface

Use the following command:

vinfra service s3 node add --nodes <nodes>

--nodes <nodes>: A comma-separated list of node hostnames or IDs

For example, to add the node with the ID 2f3f6091-0d44-45aa-94e3-ebc2b65c0eeb to the S3 storage, run:

# vinfra service s3 node add --nodes 2f3f6091-0d44-45aa-94e3-ebc2b65c0eeb

The added node will appear in the vinfra service s3 show output:

# vinfra service s3 show
