Replicate Existing Proxmox Disk Configuration on New OVH Server

[zikou]

We have identified the following disk configuration on one of our production Proxmox VE servers. Our goal is to replicate this exact setup on a newly acquired OVH dedicated server, which also comes with two identical NVMe SSDs. This ensures consistency, redundancy (RAID1), and optimal storage management for our Proxmox environment.

New Server Context:

The new server is an OVH dedicated server equipped with two NVMe SSDs, identified as nvme0n1 and nvme1n1, each roughly 900GB in size.

Task:

Please provide the detailed, step-by-step instructions required to install proxmox and configure the disks on the new OVH dedicated server to match this exact configuration
