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.

They're on virtual tin and didn’t configure properly. There are limits in the flat files you need to change by hand to get it to scale properly, it’s tricky.

Can't edit profile settings / info. Pushing Save does nothing.

Tried to comment "looking good" but can't seem to comment. Getting a timeout.

Works with Jerboa again (yay).

Kinda makes sense that multiple containers might scale better. The actual processes within the container may have some limitations in terms of how well they thread etc.

Thanks for all the work!! Now go enjoy the rest of your weekend 😋

So I can't login and the reset passwork button doesnt seem to do anything 💀

[–] [email protected] 1 points 2 years ago

@ruud Thank you for the work you guys are doing. Without you, we wouldn't have an organized place to go after Reddit and Twitter.
