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.

Thanks for the hard work!, I had an issue the first minutes where every time I logged in I got logged in with a different stranger account, now it doesn't happen but I can't login haha.

Showing us the true value of horizontal instead of vertical scaling! Kubernetes when?

Looks like everything is working well so far. Browsing from Wefwef and Liftoff.

Thank you!

Thanks for being both informative and open about this issue. Hope it works out.

Edit: The first two versions of this post didn't seem to send: spinning post button. Maybe it's not fixed or it's struggling?

I was having trouble earlier but now able to log in just fine on browser. Voting on posts doesn't seem to be working for me on desktop or apps. In apps I keep seeing error notices about votes not going through and desktop browser (Firefox) doesn't work but there's no notification there. Anyone else? Maybe everything needs a little time to sync up.

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.

What a breath of fresh air eh

[โ€“] [email protected] 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.

[โ€“] [email protected] 2 points 2 years ago

Looking good ๐Ÿ‘

Thanks for your time and effort! After the kids have gone to bed, grab yourself a beer and put your feet up!

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.
