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.

Really like seeing posts like this that explain what's going on. Thanks for all the hard work!

The transparency is so refreshing

[-] gfdoto@lemmy.world 22 points 1 year ago

Seeing this post immediately made my ditch my neglected Lemmy instance to sign up for an account on this server. Thanks for the hard work.

[-] lenninscjay@lemmy.world 29 points 1 year ago

agreed. as others have stated. Transparency. But also, new software, new tech (in a way, the fediverse/activity pub), and hopefully a new beginning. Happy to be here. If not technically on the ground level (lemmy has been around for a short time before we knew reddit was going to implode), close to it!

It's almost like we're talking to a normal human being rather than an evil overlord.

How so?

Admin communicating information about the site to users like genuine human beings, instead of the corporate-sanitized pablum reddit admins speak in? Yeah that's refreshing.

[-] Baylahoo@lemmy.world 23 points 1 year ago

It shouldn't be unreasonable but it is damn refreshing.

That was because of websockets. Which are no more in this version so yes all those "random things" bugs from multiple tabs should be fixed.

[-] sk1nnyjeans@lemmy.world 21 points 1 year ago

I was so confused by those and kept backing out my feed and going back to the post, thinking I tapped on the wrong post or maybe the app opened the wrong post. I’d scroll down and find the right comments though, I couldn’t make any sense of it. Glad I wasn’t crazy lol

Good work upgrading! I can't imagine it being too easy with a big instance.

I had issues with comments not federating to my own instance before this update (showing 0 for hours). Opening up this up now showed most of them right away if not all. Hopefully that means 0.18.1 fixed a fair few issues people had with federation.

[-] baccano@lemmy.world 50 points 1 year ago

Well done! Thank you for your efforts, cheers!

[-] stanford@discuss.as200950.com 43 points 1 year ago* (last edited 1 year ago)

For everyone experiences issues during the login,

This is caused by an issue in the latest RC of the Lemmy UI. It's already been reported, and ruud will probably decide how to deal with it tomorrow.

The current workaround
Make sure you are on the main page (https://lemmy.world) and not looking at any posts or something like that before hitting the login button.
If you encounter other issues, please make sure to clear the browser cache. The latest upgrade also made changes to the API, which can cause issues with the cached version of the website.

I cannot connect with Jerboa, it always says user or password incorrect 🙁

Edit: worked after a few minutes

[-] Sarcastik@lemmy.world 14 points 1 year ago

Same.

Just use Connect for Lemmy on Android. It's pretty good till boost gets here.

A bit off topic, but does anyone else hate how when you click on a post and then go back, the page auto-resets to the top? Wish it would remember how far down you scrolled and return to that point.

Well, I hope I'm not the only one but I cannot log in. It's been 4 hours already. Something went wrong. I'm on Firefox mobile.

--> few hours later everything is back to normal

Good bloody job admins, thank you heaps for your perseverance on this.

[-] Aurix@lemmy.world 21 points 1 year ago

When not overloaded the site works better now than ever. But in general this instancen is kind of unusable now as everything is too slow.

Am I the only one that just keeps seeing only the same 10 posts on the front page? Almost all about Reddit. Is there just no new content on this app?

[-] Ghostalmedia@lemmy.world 29 points 1 year ago

Lemmy’s sorting logic needs love. This is the first time it’s really been pressure tested with tens of thousands of simultaneous active users. Were learning that the current logic tends to promote content longer than some people like.

If people are still commenting and voting on a 3 day old posts, those post remain promoted.

[-] tburkhol@lemmy.world 13 points 1 year ago

Try different sortings. It used to default to "Active," which tends to show days-old posts. For me, "Hot" or "New" seem pretty good. Before the upgrade, anyway. Dunno if that will be changed.

So some strange behaviour: When I pressed the upvote arrows in 0.17.4, it'd immediately show this in the UI. Right now, it does not. The response appears quite slow. Is this a function of 0.18.1-rc or a function of the traffic of the Reddit-fugees?

Very nice. I see there are lots of little UI changes too. Thank you for your time and effort.

Let us know where donations can go, suspect a stacked docker-compose will reach limits very quickly

I'm not sure if this has been said but, when I open lemmy on browser, my account would sometimes be someone elses. I don't know if it's a bug and I saw it happen three times to me so far, and it even happened again a few minutes ago. It's like I i logged into someone elses account, I saw three other usernames so far. A few minutes ago it said my account was Professor -?-?-?- with that account's profile picture shown too. It only does that for half a second before it returns back to my account.

I'm just making sure this is said because I don't want to one day accidentally log into someone else's account by accident.

[-] Marxine@lemmy.world 13 points 1 year ago

Thanks a bunch for your hard work, Ruud and other admin folks! It's so damn GOOD to be able to use Jerboa again!

Also, it's really nice to see the breakdown of your work, helps a lot in understanding what you go through and maybe even of there's anything we can help with. Keep it up!

[-] Squorlple@lemmy.world 12 points 1 year ago* (last edited 1 year ago)

I'm one of the many who have had trouble logging in, and this issue is surely underreported as those affected generally aren't able to report it. It also seems like I'm not able to upvote or downvote. I'll update with any more issues that I come across but I only just now became able to log-in after a long wait and several different browsers.

Edit: it seems like I can successfully upvote/downvote, but the updated vote count and my blue/red arrow only show after refreshing the page. Thanks for all the work you put into this instance btw

Edit 2: All problems seem to have resolved now
