Resizing a Cluster Network with Instance Pools

Change the number of instances in a cluster network by resizing the underlying instance pool.

When you increase the size, instances are provisioned until the required number of instances in the instance pool are launched, subject to host capacity for nodes in the cluster's RDMA network.

When you decrease the size, instances are terminated (deleted) in the order that they were created, first-in, first-out. To remove a specific instance from the cluster network, you can detach the instance from the cluster network.

To determine whether capacity is available for a specific shape before you resize a cluster network, use the CreateComputeCapacityReport operation.

Note

The cluster network must be in the Running state to be resized.
