BCP about upgrade node in a cluster?

[dewangga]

Hi,

I am looking for best current practice in proxmox to upgrade v6 to v7 , I have 2 options here, but didn't know which is best and safest.

Option #1

- Delete node from a cluster
- Reloading node to higher version
- Joining the same node with same hostname using force join

Option #2

- Upgrading in place from v6 to v7 refers to this guide https://pve.proxmox.com/wiki/Upgrade_from_6.x_to_7.0

I have no experience about upgrade in place. And the workload was offload to another node.

Hi,

in general, I'd recommend option #2, at least for clusters with 3 nodes or more (with only two nodes it needs a bit more care for quorum, and a single-node is not a cluster)
Especially if the PVE host system was not tinkered much with it is quite easy to do an in-place upgrade. I mean, as Proxmox Staff I'm biased, but I upgraded a three node cluster with ceph and quite some guests from 6.4 to 7.0 in ~20 minutes total, without any VM being ever offline (just migrated them around).

But, if you're unsure about the in-place upgrade I would recommend setting up a PVE for training the upgrade once before, that can be done on a spare host or as VM on the existing PVE cluster. There you can even create a snapshot before the upgrade and then play it through more than once without much hassle.

I am success to upgrade in place using the wiki, thanks in a bunch for your feedback!
