Fixing discourse after disk full

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.
