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.

Thank you :)

Nice, really liking the update! Some questions about development for the fediverse: Is the code for running Lemmy written by one or person or a smome core team?

Is there any decision making process as to which features will be worked on in the next release or which bugs to prioritize?

In theory what would happen if the original developers started making changes that other people don't agree with? Would we get a fork then where servers have to choose to adopt it or not?

Thanks for the update. I especially like the transparency on not only the “upgrade” itself but also the potential issues encountered, together with the solutions. Seems rare nowadays, or I’m just seeing less and less people doing this.

[–] decadentrebel 5 points 2 years ago

Special thanks to the other guys for helping make this update possible. Site is snappier than ever and the UI looks fantastic.

I can't login from my main browser even if I clear the cache and cookies, if I use other browser it works

Edit: I fixed it just by changing my browser language to English and restarting it, hope this is useful for someone.

Also, thanks to Ruud and team for the hard work, everything seems to work really well and fast.

I survived!

It keeps logging me out, plus when I log in, alarmingly other users' profile names flash in the top right corner for a second.

[–] DelvianSeek 4 points 2 years ago

Even using Tor, the site load-times seem a lot snappier. Exciting times.

[–] MicahParsons 4 points 2 years ago

This is really cool that this gets shared. Thanks for all of the info!
