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 @stanford@discuss.as200950.com and @sunaurus@lemm.ee 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 @sunaurus@lemm.ee 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.

Seems to be working great so far.

Thank you! Your hard work is truly appreciated.

This whole upgrade process reminded me to check the patreon donation stuff for y'all.

[–] Codandchips@lemmy.world 1 points 2 years ago

Thanks very much for your time and effort Ruud, it's much appreciated! Now, after you've put the kids to bed, grab yourself a beer and put your feet up!

Question @ruud@lemmy.world 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?

The speed and responsiveness of just scrolling is already infinitely better. Thanks :)!!!

@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.

[–] bigtuna@lemmy.world 1 points 2 years ago

Thank you!

[–] Ghostalmedia@lemmy.world 1 points 2 years ago

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

[–] Myriadblue@lemmy.world 1 points 2 years ago

Thank you so much for doing this! The having an instance this big really made the difference for leaving reddit. I really missed jerboa and am glad to have it back as a client.

[–] wason@lemmy.world 1 points 2 years ago

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.
