14 days later, my postgres directory was 12GB. I was still on 18.1. Updated to 18.3 just now. Postgres directory was downscaled to 2.6GB !!! Thank you Lemmy dev's and contributors !!

pictrs isn’t even taking up that much space, postgres takes up most !

# du -sch volumes/*
8.0K	volumes/lemmy-ui
3.4G	volumes/pictrs
8.2G	volumes/postgres
12G	total

I also noticed the logs were growing and taking up quite some gb's. I've used truncate to make the syslog smaller and journalctl vacuum to keep that smaller

i'm trying to find documentation for this config but can't find any. Do you have a link maybe ?

thanks for your detailed how-to ! Will try this, hopefully it holds 2 more weeks I'm leaving for holidays now :)

the diskspace on the server I'm using for lemmyfly.org is getting full (it was 40GB local volume, and it's at 80% now) I can get extra volumes at my hosting (Hetzner) but is it possible lemmy looks at different volumes for the volumes folder that contains pictrs, postgres and lemmy-ui ?

Or do I need to move the complete main lemmy folder to this other volume and run lemmy from there, leaving my system-volume unused for lemmy ?

oh it's visible because I'm admin/ mod ?

actually I did delete the server (after creating a snapshot of it) a week or so ago. But this morning I wanted to check lemmyfly.org, couldn't load the page. Checking my Hetzner dashboard I noticed CPU was spiked at 200%?! It did drop again though, but apparently had last for 2-3 minutes. But prometheus was down, so no graphs apart from the hetzner ones. I doesn't relate to network traffic spikes, so I don't know what caused it. I've started the prometheus server again (that snapshot was really useful :) ) and will leave it on for a couple of months now.

current system consumption:

I might need to get an extra volume for storage, Lemmy is starting to eat up the root filesystem.. Does anyone know how I re-configure Lemmy to look at a different volume for storage ?

I've set registration to Require application again, don't like this bots creating accounts.

Also I'm running into email limitations. Using the Sendgrid Free plan of 100 emails per day, but if a couple of member have email notification on, I'm reaching that 100 very quickly. How do others handle the high email traffic ?

running a lemmy instance has learned me a lot about devops already!

I love playing around with this, the lemmy instance was a great reason. lemmyfly.org doesn't have a lot of traffic yet, I think it can handle some more. Currently running on 2 vcpu/4gb ram.

After chatting to my devops colleague at work I wanted to set up a Grafana dashboard with metrics on the server. Seems it's pretty pretty doable!

  • I installed prometheus node_exporter on my lemmy server
  • I created a second server at my VPS. Very cheap, and don't think I'll be running the Prometheus/Grafana 24/7 so I'll just create a snapshot of it, destroy the server and re-create when wanted
  • Created an internal private network so the instances can communicate without exposing ports to the public
  • Installed Prometheus on the new prometheus server
  • Installed Grafana
  • log in to Grafana, admin:admin then change password
  • Go to the Grafana home dashboard, click on + sign and click on Import. In Import via grafana.com, put the dashboard id 1860 (preset for all prometheus node_exporter metrics) and click on Load.
  • Done!

Last 2 hours in the garden with a beer on the side, WFH FTW

When the admin of a instance wants to stop the server (for example costs are running too high) but your communities are active and you don’t want them to die along with it, is it possible to migrate the communities to another instance?
