Upgrading Proxmox & CEPH from 6.0 to 6.4 to 7.1

[smguenther]

Hello,

I recently became responsible for a three node cluster which is still running on 6.0.

I already checked the documentation on https://pve.proxmox.com/wiki/Downlo...Proxmox_Virtual_Environment_6.x_to_latest_6.4 but I still have a question, because I'm a little bit concerned about CEPH:

Should I first update the first node from 6.0 to 6.4, then reboot it and repeat the procedure for the other two nodes? Or should I update all nodes at the same time and then reboot all three? The same question comes up when updating from 6.4 to 7.1.

Thanks for any suggestions,

Stefan

its safe (and correct procedure) to reboot em one at a time.
