How to clear cache or make some space available for my instance?

cross-posted from: lemm.ee/post/15339951

My Lemmy instance has reached 100% storage so I can no longer use it. Is there a safe way I can clear cache or make some more space available without upgrading the disk space? I set up the instance with the ansible script many months ago and migrating to object storage seems to be a decent amount of work I don’t have to commit to currently.

I tried searching on the admin wiki (wiki.lemmyadmin.site) but I couldn’t find anything

I can’t switch to Object Storage just yet because I’m worried that since I have 0 space left there will be issues when trying to migrate so I need to make some space available and then make the switch to Object Storage

I don’t have good advice for right now, but as for the future: always have a 5-10GB file on your server that you can delete in an emergency.

xnx OP ,

good idea

Look at root reserved blocks on ext4, this is already the default

What’s your filesystem? What is your storage setup currently? Can you get to a shell on the running OS?

You might want to boot to a live linux usb/disk/ISO mount your filesystem/drive that is full and delete your cached files from that.

I would strongly suggest standing up your self hosted instance in a docker container if you haven’t already

Also now might be a good idea to look at grabbing a cheap external drive and backing up to that as a worst case.

xnx OP ,

im running ubuntu on a vps. I can get a shell running. I don’t see where in that thread it mentions how to clear the tables?

I set up Lemmy using the Ansible setup so it is in docker

I have backups automatically running every week.

I believe you want to look at the activity table. I don’t have an instance, but the linked thread mentions it.
