Hmmm is there a way to add more disks to an existing Hetzner machine? I definitely do not see a UI for that. Maybe I'd need to contact customer support for that? Did anyone do this before?
Still if I wanted to upgrade everything in place, I would have to take the replica server offline, and last I did that the difference was somewhat noticeable, so in the end I might have to add another machine to the cluster permanently.
@saper Well, I am not going to upgrade the PostgreSQL version as there is no need. I mean, 10 sounds nice, but I think it would be unnecessary risk and I can't use the new features in Mastodon code yet because most people will still be on 9.6
@saper I don't remember where I read it but I think Hetzner takes the machine offline to install a new disk. If you think about it, they have to take it from the rack and put a piece of hardware inside, so it kind of makes sense.
