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 voilร . 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.

You know, this is a nice post because now I understand what was happening to me as a user. Thanks for confirming that I am not insane! Well, maybe I'm insane, but what I was trying to do and couldn't was real, not something I was doing wrong. Also, thanks for updating the stuff that makes it work.

[โ€“] [email protected] 2 points 2 years ago (1 children)

[โ€“] FinalBoy1975 2 points 2 years ago

It's nice, yes. I really hope people catch on to these things about transparency. The aren't seeming to, but maybe they will and we'll live in a better world.

On a somewhat related note, how are you coping with the scaling from the Reddit migration?

Thank you for al the work. Do you have a need or plans for community help at all? Outside of content moderation? Not quite sure how I could help but I do software for a living.

Question @[email protected] why update to the release candidate? Just want to help testing? Or was there some readdition (ie: captcha) that had you quick on the trigger?
