Deploying a Linstor Cluster

For this lab, you have been asked by a customer to help them set up a Linstor cluster. They would like you to set up their Linstor servers, storage, and create a new resource for them. Upon completion of this lab, you will be able to set up Linstor controllers and satellites, configure storage for use in Linstor, and create Linstor resource and volume groups. In addition, you will be able to create Linstor resources and use them on the local cluster.
