Linux: Deploying virtual grid nodes

You can deploy virtual grid nodes on new Linux hosts or on existing Linux hosts. If you need additional Linux hosts to support the CPU, RAM, and storage requirements of the StorageGRID Webscale nodes you want to add to your grid, you prepare them in the same way you prepared the hosts when you first installed them. Then, you deploy the expansion nodes in the same way you deployed grid nodes during installation.

Before you begin

If you plan to deploy new virtual grid nodes on existing hosts, you have confirmed the existing hosts have enough CPU, RAM, and storage capacity for the additional nodes.
If you plan to deploy new virtual grid nodes, you are minimizing failure domains. For example, you should not deploy all API Gateway nodes on a single physical host or deploy multiple Storage Nodes from the same site on the same physical host.
You have the appropriate StorageGRID Webscale Installation Guide.

Steps

If you are adding new hosts, access the Installation Guide and locate the instructions for "Deploying StorageGRID Webscale nodes."
Follow the instructions in "Preparing the hosts" to deploy the new hosts.
Follow the instructions in "Deploying virtual grid nodes" to create node configuration files and to validate the StorageGRID Webscale configuration.
If you are adding nodes to a new Linux host, start the StorageGRID Webscale host service.
If you are adding nodes to an existing Linux host, start the new nodes using the storagegrid host service CLI:sudo storagegrid node start [<node name>]

After you finish

After deploying all new grid nodes, you can perform the expansion.
