One of the common needs of a cloud platform is to scale resources as compute and storage needs expand. Over time there is often a need to add additional compute resources, as the required Virtual Machine (VM) growth has exceeded planned capacity, or to remove or repurpose nodes. Likewise, storage resources must expand or contract to match demand. Compute nodes are used for hosting VMs, and storage nodes are used for hosting Red Hat Ceph Storage version 1.3.2, which manages block, image, and ephemeral storage, in the Dell EMC Red Hat OpenStack Cloud Solution.
This technical guide explains the process of adding or removing a Dell PowerEdge R730/R630/R430 compute node or R730XD storage node in an existing cluster in the Dell EMC Ready Bundle for Red Hat OpenStack Version 6.0.1.
