Hi,

I know this is quite impossible to diagnose from afar, but I came across the posting from lemmy.world admins talking about the attacks they are facing where the database will get overwhelmed and the server doesn't respond anymore. And something similar seemed to have happened to my own servers.

Now, I'm running my own self-hosted Lemmy and Mastodon instances (on 2 seperate VPS) and had them become completely unresponsive yesterday. Mastodon and Lemmy both showed the "there is an internal/database error" message and my other services (Nextcloud and Synapse) didn't load or respond.

Login into my VPS console showed me that both servers ran at 100% CPU load since a couple of hours. I can't currently SSH into these servers, as I'm away for a couple of days and forgot to bring my private SSH key on my Laptop. So, for now I just switched the servers off.

Anyway, the main question is: what should I look at in troubleshooting when I'm back home? I'm a beginner in selfhosting and I run these instances just for myself and don't mind if I'd have to roll them back a couple days (I have backups). But I would like to learn from this and get better at running my own services.

For reference: I run everything in docker containers behind Nginx Proxy Manager as my reverse proxy. I have only ports 80, 443 and 22 open to the outside. I have fail2ban set up. The Mastodon and Lemmy instances are not open for registration and just have 2 users each (admin + my account).

Hi there, If I'm looking to use LLM AI in a similar way like Stable Diffusion, i.e. running it on my own PC using pre-trained models (checkpoints?) - where would I start?

If I would want to have access to it on my mobile devices - is this a possibility?

If I would then later want to create workflows using these AI tools - say use the LLM to generate prompts and automatically run them on Stable Diffusion - is this a possibility?

I'm consistently frustrated with ChatGPT seemingly not beeing able to remember a chat history past a certain point. Would a self-run model be better in that regard (i.e. will I be able to reference somethin in a chat thread that happened 2 weeks ago?)

Are there tools that would allow cross-thread referencing?

I have no expert knowledge whatsoever, but I don't shy away from spending hours learning new staff. Will I be able to take steps working towards my own personal AI assistant? Or would this be way out of scope for a hobbyist?

So, I have some idea on what a reverse proxy does and will be using nginx (with the neat proxy manager UI) for my setup.

However, I'm not completely clear what exactly I want it to do and how I cn use it to run different services on one machine. I'm especially unclear on the ports configuration .... tutorials will say things like "change the listening port to xxx for that service and to port yyy for the other service"

How does this work, which ports can I use and how do I need to configure the respective services?

EDIT: thanks everybody, your replies did help me a lot! I have my basic setup now up and running using portainer + nginx + fail2ban.

Hi, I'm new with self-hosting but managed to set up my own Lemmy and Mastodon instances on a VPS recently. However, I ran into an issue with disk space quite rapidly (which I had way too few, because I started with the cheapest, smallest package for my VPS).

Now I prepare a new setup, where I'll be able to dynamically scale disk space as needed, but this can get expensive quickly. Therefor my question: How much disk space do I typically need for private (1-3 user) instances of Lemmy and Mastodon? Are there settings, where I can limit the disk space utilization (at the cost of older stored content being overwritten)?

I would be fine with needing up to like 30-40 GB, but any more than that would be getting kinda expensive ....

Out of curiosity I'm currently considering to self-host a Lemmy and a Mastodon instance. Just for me (and maybe 2-3 close friends) privately. The proposition of having full control over my social media sounds appealing to me.

However, I'm not a software developer and I have next to no experience in self-hosting anything. Also, I don't plan to make self-hosting a hobby of mine.

Given these circumstances - how much time investment do you think is needed to keep everything running smoothly. I wouldn't mind spending 1-2 hours a week, but if it's more like 1-2 hours a day, I would stay clear.

Also, are there resources for troubleshooting available? I found the installations guides and some seem to be quite good for a layperson, giving step-by-step advice, however where to go if it doesn't work?

I'm trying to make up my mind if it would be worthwhile to try or if I set myself up with wasting a lot of time :) So, any advise is welcome.
