Looks like it works.

Edit still see some performance issues. Needs more troubleshooting

Update: Registrations re-opened We encountered a bug where people could not log in, see https://github.com/LemmyNet/lemmy/issues/3422#issuecomment-1616112264 . As a workaround we opened registrations.

Thanks

First of all, I would like to thank the Lemmy.world team and the 2 admins of other servers @[email protected] and @[email protected] for their help! We did some thorough troubleshooting to get this working!

The upgrade

The upgrade itself isn't too hard. Create a backup, and then change the image names in the docker-compose.yml and restart.

But, like the first 2 tries, after a few minutes the site started getting slow until it stopped responding. Then the troubleshooting started.

The solutions

What I had noticed previously, is that the lemmy container could reach around 1500% CPU usage, above that the site got slow. Which is weird, because the server has 64 threads, so 6400% should be the max. So we tried what @[email protected] had suggested before: we created extra lemmy containers to spread the load. (And extra lemmy-ui containers). And used nginx to load balance between them.

Et voilà. That seems to work.

Also, as suggested by him, we start the lemmy containers with the scheduler disabled, and have 1 extra lemmy running with the scheduler enabled, unused for other stuff.

There will be room for improvement, and probably new bugs, but we're very happy lemmy.world is now at 0.18.1-rc. This fixes a lot of bugs.

Browser still not working for me. The interface loads but there's no content. Also can't login on browser, after entering user and password and clicking login nothing happens.

I had the same problem on lemm.ee when that admin upgraded it. In my case, it only happened when I was on Firefox on the desktop. It happened because I had Spanish installed as a display language.

If you have more languages than just English installed in the browser, remove them, close the browser, re-open the browser and see if it works. @https://lemmy.world/u/ruud, If you see this, ask @https://lemm.ee/u/sunaurus what he did to fix the issue on the backend.

I did a write-up on what I tried. My username is the same on lemmy.world as it is on lemm.ee.

Thanks! That was it. I'm using Firefox on Android. Changed language to English (US) and it worked! @[email protected] can you please check this issue? using a browser with a default language other than English will result in the page not loading correctly. Workaround is just setting the browser language to English. Thanks!
