Hello everyone, I'm beginner with proxmox and i have a question. To create my cluster proxmox I use 3 nodes with physical RAID 5. But full video and documentation show me nodes without physical RAID and cephFS cluster for shared storage. In addition proxmox say "cephFS dont work with hardware RAID". I think CephFS is the best practice for shared storage but It'is possible to create shared storage with other (ZFS / DRBD ...), if yes it is a good option or not ?

Thanks for your help. Best regards

Ceph is mainly recommended in a hyper-converged infrastructure (HCI) setup, where storage and compute scale together across nodes. It shines in environments that need high availability, self-healing, and scalability.


But if your goal is just shared storage and not a full HCI design, then using something simpler like NFS or SMB/CIFS is often the better choice. They’re easier to set up, require fewer disks and networking considerations, and integrate smoothly with Proxmox.


So, use Ceph when you want a real HCI cluster, but if you just want shared storage, NFS or SMB/CIFS is the recommended option.

Thank you for your reply. I don’t have a specific goal, I’m just experimenting with this technology. Right now, I’m trying to set up shared storage between all nodes for high availability with my VMs. If node 1 goes down, I want all my VMs to be able to run on node 2 or 3.

To have a good formation, do you know a good formation maybe ?

Thanks

If you just want to try HA in a simple way, I recommend setting up a NAS and adding it to Proxmox as NFS storage. That will let all your nodes access the same VM disks, and you can experiment with HA failover without the complexity of Ceph.

Yes i tried this, I configured a CIFS storage with NAS and all was ok. But all my nodes owns physical disk in physical hardware and i don't want lose this storage. So what is the best option to use this local storage with RAID and make a share storage for my cluster ?

Thanks
