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?

@Gargron ah sorry, didn't expand properly. This assumes dedicated.
@saper I have dedicated servers!
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 Yes, I need a bigger storage capacity for the database
@Gargron This is not the same thing :) ... What kind of replication are you running now?
@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
One master and one hot streaming replica.
@Gargron You could add another replica, yes. Are there reasons why you can't expand the filesystem live?
@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.
@Gargron Since ~1997 SCSI disks could be added live to the system, I guess your box can do it. That's the way dead disks are getting replaced in RAID.
@saper LVM/ext4 I think
Did you hear about
I have unfortunately no experience with them, so I'd need to do lots of testing before jumping water.
In the meantime, adding a disk and designing better and less wasterful schema may help :)
@Gargron hugh hetzner
@Gargron depends on your subscription. You should talk to the support.
@Gargron sounds like a customer service / give us money thing
