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.

The instance just got so much more faster and stable, it's amazing. Keep up the good work!

I'm sure there will be bugs for others but it's smooth and bug free for me. Thanks so much for the devs and contributors.

Lot of network errors, but it could be jerboa.

[-] Grangle1@lemmy.world 6 points 1 year ago

Login problem is fixed for me, yay! Back on Jerboa and here on the browser! Thanks for your hard work and for putting up with me, lol.

I'm getting network errors that aren't allowing me to actually view content on Jerboa right now, though, but at this point I'm assuming it's a Jerboa thing and not a problem with the instance.

🎉 Great work!

[-] newthrowaway20@lemmy.world 6 points 1 year ago

Having login issues on the browser. Not logging in at all. But on liftoff where I was already logged in, everything seems to be working.

[-] Yaxoi@lemmy.world 6 points 1 year ago

I'm curious; is this instance pysically running on a local private server somewhere or in the cloud in some data center?

To everyone having a login problem, it seems that resetting the password solves the issue! Maybe this means that the upgrade corrupted the stored hashes somehow?

@ruud oh wow 0.18.1 fixed the broken federation/webfinger issue!!! this is great news

[-] Secret300@lemmy.world 6 points 1 year ago

we created extra lemmy containers to spread the load. (And extra lemmy-ui containers). And used nginx to load balance between them.

Had no idea nginx did that. There's so much I need to learn

[-] erik1984@lemmy.world 6 points 1 year ago

Thanks for the hard work on the upgrade! Much appreciated although I'm only using the web version (not needing specific client apps). Lemmy World feels quite 'snappy' when browsing now.

[-] varnia@lemmy.world 6 points 1 year ago

Updated Jerboa. Thanks for your efforts, transparency and insights.

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?
