Quick check on future upgrade

[cfgmgr]

Greetings!

I'm now recently in charge on an (olderish?) Proxmox cluster. It is a little behind in updates and want to confirm at a high level a step or two as I plan to start getting this setup current.

Hardware - we have 4 of these
Supermicro SSG-110P-NTR10
Single Intel(R) Xeon(R) Gold 6312U
512GB of memory
3.84TBx6 Kioxia drives per node

Since this is running ceph - this document is a key piece for the upgrade since I'm currently on 16.2.9 and need to get to 17:
https://pve.proxmox.com/wiki/Ceph_Pacific_to_Quincy

Question I have is... Should I upgrade Ceph first, or should I get to PVE 7.4 before doing ceph? Any known issues or gotchas?

There is a PBS server in the mix too. That is 2.2-6 and I need to keep that into consideration.

Thanks!

Hi,

for this we have a very detailed Upgrade from 7 to 8 wiki page / upgrade guide.

To shortly address some of your question right here (which also should all be answered in the guide):

You should update to PVE 7.4 first. then upgrade your Ceph cluster from Pacific to Quincy and then upgrade PVE to 8.0.

Any known issues or gotchas?

For this sort of thing, I recommend checking the roadmap for breaking changes: Roadmap - 8.0 breaking changes.

There is a PBS server in the mix too. That is 2.2-6 and I need to keep that into consideration.

The same guide also exists for PBS: Upgrade from 2 to 3, and it's roadmap: Roadmap

Thank you Christoph - I knew I skimmed that 7to8 wiki but I was thinking in the context of going to 8 and wasnt quite there yet. Missed a few details at the top.

I will get PVE updated to 7.4 before tackling Ceph - thank you again for the clarification and the wiki link!

Just to update this...
Upgraded Proxmox to 7.4. Following day upgraded Ceph.

Went very smooth and no issues.

Thanks!
