The following procedures add a server pool to an existing MinIO AIStor cluster running on bare-metal infrastructure. Each pool expands the total available storage capacity of the cluster while maintaining the overall availability of the cluster. A new pool is a set of new nodes and drives that meet the cluster’s erasure set requirements and parity levels. You can use MinIO’s Erasure Code Calculator to check the Erasure Code Stripe Size (K+M) of your new pool to confirm that it meets the EC:M value of current cluster. MinIO strongly recommends seeking an architecture review from MinIO Engineering through SUBNET to analyze potential performance impacts before committing to a new pool for your cluster.
