Upgrading root disk on PVE host in a cluster?

Hi All

Homelab environment.
System 1: Supermicro X10SDV, 8C/16T, 64GB.
256GB NVMe (as system and some for lvm-thin)
1TB SATA SSD (as ZFS pool, shared via NFS)
4x SATA disks as ZFS Pool shared via NFS

System 2: Intel NUC, 2C/4T, 16GB
512GB SATA SSD

Configured as a proxmox cluster.

Bunch of other storage via NFS available to both.

I recently have needed to use a bunch more VMs (20+) to simulate new environments and found disk is slow... So, I'm about to receive a new 1TB NVMe drive for the proxmox host (to replace the 256GB NVMe drive). I can move the key VMs to this to give it the boost it needs.

I've backed up all VMs to remote NAS via NFS.

I don't own anything that can hold two NVMe disks, so cloning the current disk is a non-starter.

I plan to fresh install proxmox on the new disk.

Question: What's the most straightforward way of adding the newly installed machine to the cluster to replace the "old" one?

Thank you!
 
Hi,

remove the old node with
Code: 
pvecm delnode <nodename>

remove the node dir in the /etc/pve/nodes/<nodename>
add the new installed node to the cluster

Oh - cool. As simple as that!

Do I need to remove the old node before I power it down for re-installation? Or can I do it afterwards?

You can choose ;-)
The command must execute on the cluster, not on the node self.
