Advice I added most likely ;) "RAID controllers" *are* a subset of HBAs BTW.

I believe I remember knowing that RAID controllers are sub optimal but I guess
I don't understand how you would

Podman does not come with a daemon to start containers.
The Ceph orchestrator creates systemd units to start the daemons in
podman containers.

Podman doesn't use a daemon, thats one of the basic ideas.
We also use it in production btw.

That's good to know, I have the same in mind for one of the clusters
but didn't have the time to test it yet.

I even converted clusters from Docker to podman while they stayed online

I would strongly recommend k8s+rook for new clusters, also allows

Why would I want to learn Kubernetes before I can deploy a new Ceph

What is the advantage of podman vs docker ? (I mean not in general but for
ceph).
Docker comes with the Docker daemon that when it gets an update has to
be restarted and restarts all containers. For a storage system not the

migrating to cephadm.
