Hello all,

I have a Proxmox setup where the operating system (Proxmox VE) is installed on NVMe1, and all my VMs are stored on a separate drive, NVMe2. NVMe1 is showing signs of wearout which is increasing (88%) and I want to replace it before it fails.

I am nervous about doing this and would appreciate guidance on the best and safest approach to:

  1. Replace NVMe1 (system drive) without affecting the VMs on NVMe2.
  2. Preserve Proxmox configuration, settings, and VM definitions.
What are the best practices or step-by-step instructions to accomplish this?

How is the system installed? If ZFS is installed as the root OS you have some more options. Can you add the replacement NVME as an additional disk or do you need to remove the current OS NVME to make space?

it is a dedicated server, have full remote access to it and maybe can have a 3rd NVME installed, not sure if ZFS installed but I have NVME1 that is the main boot that have proxmox installed on, and my VMs are using my 2nd NVMe drive. I want to install fresh proxmox on new NVMe and then reimport my VMs. I need a correct way to backup config of proxmox VMs then import my VMs with data.

sorry maybe I didn't clarify my question properly
