Share disks between 2 Proxmox machines

[Bookmaster]

Hello Proxmox community,

I have two physical servers, each running Proxmox 7.2-3, with several disks on each of them. I want to enable the sharing of the "vmdata2" partition between these two Proxmox instances. This way, both Proxmox servers can access the same data and disks.

Can someone kindly guide me through the process of setting up shared storage between the Proxmox servers using either NFS or Ceph? I'm looking for step-by-step instructions and best practices to ensure a successful configuration.

Any advice, tutorials, or personal experiences with setting up shared storage on Proxmox would be greatly appreciated.

Thank you all for your help!

Best regards,

Bookmaster

You can start here https://pve.proxmox.com/wiki/Deploy_Hyper-Converged_Ceph_Cluster
Keep in mind that "two" is not a supported/recommended number of servers for both Ceph and PVE cluster. It may be ok for playing in your home lab.

Thank you bbgeek17
Then it should be NFS. Could be NFS used for my "case", please?

Why do I want to do that?
I want to use that shared disks for backups and avoid NAS.

Best regards

In which case, your question isn't really Proxmox specific. You're talking about a generic principle of exporting a filesystem/director via NFS, to mount from a remote server. Is "vmdata2" used exclusively for backups?

Yes.
I would like to make backup from one Proxmox to another. On both of them I have windows VM's but just one Proxom has windows server that I want to backup on another Proxmox vmdata2.

You can use NFS to create two independent pools of storage and access them from either host, both for backups and VM images.
The data will not be redundant and if one host or disk dies, you will loose that data.

Thank you, but that disk is already in mirror mode, I mean there are 2 disks there shown as one, vmdata2.
I am not really into "material" and this is obvious but I think there must be a way to make these shares for backup.

in that case the single point of failure is your server. Its your data - you decide what's enough.

I will take risks. Could you direct me to instructions for NFS, please?

One of the results from this google search query "how to setup nfs server on debian" should work just fine.
Then follow by using information here: https://pve.proxmox.com/wiki/Storage:_NFS
