Fixing discourse after disk full

Installation
1

My AWS ec2 instance ran out of disk space (it has 16GB). I ran rm -rf /var/lib/docker/overlay2 and journalctl --vacuum-time=10d to free up space, and now df says I have 7GB of free space. after rebooting the instance I get Connection refused when trying to connect to the page.

I tried sudo ./launcher rebuild app but it fails saying there less than 5GB of disk space.

Any suggestions?

25GB is usually the recommended minimum. Even if you can get it back up running with your current allocation this is going to happen again with such a small volume.

Just to note, Hetzner’s lowest tier offers only 20GB, but that’s been working for me. It can be worth tidying up the backups directory before trying an upgrade: having, of course, taken a new backup and copied it elsewhere for safety. (It’s a small forum: a backup is 120MB.)

In another case, I use Digital Ocean’s lowest tier, offering 25G, and in that case the forum’s backup comes in at 640MB.)

The one time I had trouble, it was the journal thing, but I cut that right down:

# journalctl --disk-usage
Archived and active journals take up 104.0M in the file system.

Ok, I have increased the size of the disk so discourse-doctor sees 40G (29% used) so space is no longer the issue. I need help getting discourse up and running.

sudo ./launcher start app fails with
Unable to find image 'local_discourse/app:latest' locally

The failing output of sudo launcher rebuild app is here

How do I fix this?

ok I got sudo launcher rebuild app to work by changing “templates/postgres.template.yml” to “templates/postgres.10.template.yml” in app.yml

Should I leave that change, or change it back and try rebuilding?

I think you need to visit the postgres update thread and ask for help…
