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 voilΓ . 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.

Half the time when I comment, it just spins. :( Edit: Apparently when I comment it posts, but just shows spinning until I manually refresh. Must be on my end.

It seems that I can't log out in my browser. The page simply reloads after clicking the button.

πŸ™Œ Great work team!!!

Is there a way to follow the update status while this instance is down?

I knew the update was coming, so I expected the downtime, but I could not find any info about when it was expected to be up and running again?

Thanks for the great and ongoing work put into managing this endeavor!

Love the update, all back up and running again :) I joined this morning after discovering this awesome Apollo replacement and was so disappointed that it was down already! Understand that the sudden surge must be huge, looking forward to seeing the data of amount of users gained by Lemmy!

Honestly praying this is the solution we all want and need!

Thanks so much for all your hard work, love Lemmy world! Enjoy the time with family!
