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.
Thanks a lot for your hard work, take your time with your children

This post encapsulates what I love about this place.
It’s almost like we’re talking to a normal human being rather than an evil overlord.
I for one welcome our new benevolent overlords
Don’t blame me, I voted for Kodos

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.
It shouldn’t be unreasonable but it is damn refreshing.
It’s cool we all want the new community to succeed and get live updates on things being fixed or worked on. There’s some shared misery in growing pains/bugs as we all stress test the system, but I think that only somehow brings more communal joy when the problems are fixed.
Agreed. Thanks for letting us nerd out
Really like seeing posts like this that explain what’s going on. Thanks for all the hard work!
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.
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.
Huge thanks to the lemmy.world team over the last couple of days to scale and maintain the instance! There’s a link for donating on the sidebar for lemmy.world - just a couple bucks a month can help us support this instance!
Well done! Thank you for your efforts, cheers!
I cannot connect with Jerboa, it always says user or password incorrect 🙁
Edit: worked after a few minutes
Looks like the server is choking again, we’ve had ~7k new signups so far today 😅
Congratulations! I can’t believe how much you get done, Ruud! You are crushing it
This guy is on fire!
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
You can send a reset password, and the link to reset the password will log you in as your password is updated.
However, the login button remains broken, even after password reset. Still, this provides us a 2nd way in if your browser cache gets cleared.
The XHR for the button reports back a 404 error, suggesting that login page just stopped existing after the update. I’m assuming that it will be an easy hotfix, just gotta fix the link to the POST form to point at wherever the login page went.
Should work now
I’m having the same issue too, including after clearing cache and trying incognito etc.
I am having the same issue. I’m in with Mlem, but I can not log in on the site. I even tried it with content blockers off in case there was a captcha or something being blocked.
(Safari on iOS)
Get the same but also in addition it happens in Liftoff.
This needs to be higher. It happens on all browsers and on jebora as far as I can tell.
It drove me nuts too and I hope admins remove the “clear your browser cache” advice from the homepage, because that will simply lock you out of your account if the login form is broken.
Right now the login form seems to work again though? Can you try again?
Clearing the browser cache should fix the issue :)
Unfortunately it does not, everyone having the same issue try to create account on different instance and comment on this bug in here.
Didn’t work for me on Jerboa. I cleared the app data, but I’m I still not able to login.
Edit: I’ve tried again just now and I could login on Jerboa.
I can’t get into my sh.it acct on Jerboa either.
Mh… some people said they tried a password reset
But I can’t confirm if this is workingI have this issue on my own instance. Neither Jerboa or Liftoff can log in to my main account (no errors or anything), but for some reason my admin account (one that pretty much sees no activity) works just fine. Thunder seems to be the only app aside of the web ui that works. Maybe an 0.18 issue?
I’ve tried multiple times. It doesn’t.
it has nothing to do with cookies (and my advice is to NOT clear your cookies if you have a working session), the login form is (was?) broken, the API endpoint for the login kept returning a 404 status code
Mh… the login endpoint seems to work
Could you please share some more information?
Mh… the login endpoint seems to work
Yes, only now, shortly before I typed that comment the endpoint always returned a 404 error.
Could you please share some more information?
It was a server-side error, many users in the comments confirmed it multiple times and it was a bit surprising that none were acknowledged: it had nothing to do with browser cache or cookies, the login was broken. Ruud finally acknowledged that it’s a bug related to closing registrations. Apparently closing them prevents user login.
But the cookies are set just for the path
It’s weird that people seem to be having very different experiences with this. Liftoff says it’s logged in for me on my ‘world’ account, but posting/checking account details doesn’t work - Jerboa won’t login, resetting the password works once on the web, but subsequent logins don’t work.
Lemmy feels much smoother now after hours of being overloaded, what changed?
Thanks again admin team, you rock!
Let us know where donations can go, suspect a stacked docker-compose will reach limits very quickly
Good bloody job admins, thank you heaps for your perseverance on this.
Can I actually post from Jerboa now?! Edit - Great success!!
