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 |
