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 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.

Seems to work good enough!

[โ€“] ami@lemmy.world 3 points 1 year ago

Amazing work! It seems much more performant now, everything seems to be loading faster.

[โ€“] nucleative@lemmy.world 3 points 1 year ago

Working well here and can use Jerboa again. Although wefwef is really growing on me!

Edit: couldn't post from Jerboa, got network error. But wefwef worked.

obviously not critical, but it looks like there's a small sidebar bug (or feature?) that puts the pic near the instance name if it is the first thing in its description?

I think that's a feature. But not 100% sure ๐Ÿ˜…
But honestly, I like the look. If it is a bug, it should become a feature ๐Ÿคฃ

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

Running so many Lemmy instances against the same database doesn't cause race conditions? I wonder why that "just worked" so easily, usually load balancing DB-backed apps is a whole beast on its own.

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

Thank you!

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.

[โ€“] Jodilye@lemmy.world 2 points 1 year ago

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!

[โ€“] GwilliamSP@lemmy.world 2 points 1 year ago

Amazing! Thank you ruud and everyone who helped you push through it.

[โ€“] spasm01@lemmy.world 2 points 1 year ago (1 children)

I cannot see my subscriptions, not sure if its me or what. On Jerboa 0.34

[โ€“] EyesInTheBoat@lemmy.world 3 points 1 year ago (3 children)

Does this problem still occur on the latest stable Jerboa build? I have a feeling it may be the breaking changes in 0.18.x+ causing this

[โ€“] Gort@lemmy.world 2 points 1 year ago

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?

Hey ruud. Is there Patreon we can sign up to help with the hardware upgrades/upkeep?

Waiting for the part where this instance moves to a k8s cluster

[โ€“] JoMiran@lemmy.world 2 points 1 year ago (1 children)

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