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.

YAY! Looks like federation from lemmy.world is working a heck of a lot better now with my instance!

thank u for letting us know what happening behind the scene. Me myself is a sysadmin and really love to read story about scaling up servers and it actually works! Once again. Thank you.

Would you mind sharing your docker-compose.yml file (sanitized, of course)? I am trying to spin up an instance on Google Cloud.

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.

Thanks for the monster effort on the update, these things are never trivial.

Clearing the cache seems to have fixed the login bug.

There is another big going on where I'm seemingly logged out all the time though.

[–] [email protected] 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!

[–] [email protected] 1 points 2 years ago (2 children)

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?

@ruud Thank you! This is an important one for the community! And maybe the servers too. ;)
