This is the official guide here from OpenEBS. Step 1.) Make sure you have the right version. As of this time 2025-04, we need Kubernetes/Microk8s version 1.23 or higher (note this will continue to increment higher). Usually a good sign of having the wrong/old version is that you will encounter namespace and other errors: error: unknown flag: --namespace........

Yes you have that right, the network service in RHEL8 / CentOS 8 / Rocky Linux / Alma Linux no longer exists. So there is no more systemctl restart network You can restart NetworkManager but it doesn't have the same effect or ifup/ifdown on all interfaces. Generally if NetworkManager is installed you will want to restart it or it won't apply the settings from ifcfg. systemctl restart NetworkManager To repl........

1.) Replicate the number of partitions in your new drives. gdisk /dev/sda gdisk /dev/sdb I created 3 partitions of the same same size. partition #1: +1G (/boot) partition #2: +60G (swap) partition #3: rest of it (/) #note if you are using GPT/gdisk you need to create separate a partition at least 1MB in size (in my case I would a 4th partition and mark it type ef02).........
