Hi Hervé,
No answer from me, but just to say that I have exactly the same upgrade
path ahead of me. :-)
Please report here any tips, trics, or things you encountered doing the
upgrades. It could potentially save us a lot of time. :-)
Thanks!

Dear list,
I am currently in the process of upgrading Proxmox 4/Jewel to
Proxmox5/Luminous.
I also have a new node to add to my Proxmox cluster.
What I plan to do is the following (from
https://pve.proxmox.com/wiki/Ceph_Jewel_to_Luminous):
* upgrade Jewel to Luminous
* let the "ceph osd crush tunables optimal " command run
* upgrade my proxmox to v5
* add the new node (already up to date in v5)
* add the new OSDs
* let ceph rebalance the lot
A couple of questions I have :
* would it be a good idea to add the new node+OSDs and run the "tunables
optimal" command immediately after, which would maybe gain a little time
and avoid two successive pg rebalancing ?
* did I miss anything in this plan?
Regards,
Hervé
