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 @[email protected] and @[email protected] 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 @[email protected] 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.

It's faster now, and we finally have buttons for rich text features! Congratulations!

Update: upvotes are a bit broken and weird right now, I need to refresh every time to see that I upvoted. But that's really the only issue I see right now.

[–] [email protected] 7 points 1 year ago

Awesome to see the transparency and some tech details of what these updates entail! I’m loving the bug fixes 0.18 brought too

[–] [email protected] 7 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!

[–] [email protected] 6 points 1 year ago

Hey, thanks for your hard work, just want to let you know that login doesn't work for me in incognito mode or on any app.

[–] [email protected] 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.

[–] [email protected] 6 points 1 year ago

Lemmy seems pretty slow. I wonder how many more people have joined here now.

[–] [email protected] 6 points 1 year ago

Thank you from England for all the hard work AND for giving such interesting details, especially as it will encourage others to set up their own instances, and help them cross similar hurdles!!

[–] [email protected] 6 points 1 year ago

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

[–] [email protected] 6 points 1 year ago

thank you for letting us know behind-the-scene stuffs.

me myself is a sysadmin and really like story of successfully scaling up servers. very satisfy to hear.

once again, thank you!

[–] [email protected] 6 points 1 year ago

Lot of network errors, but it could be jerboa.

[–] [email protected] 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.

[–] [email protected] 6 points 1 year ago (1 children)

So, basically I can't see any content from lemmyworld, I'm commenting right now from another instance. When I logged into my Lemmy world account its just empty, zero content, any solutions?

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

[–] [email protected] 6 points 1 year ago* (last edited 1 year ago) (6 children)

I am still getting errors half the time I do anything while using jerboa

Website is working great though

Edit: It's suddenly working a lot better now. Hopefully I am not jinxing myself.

[–] [email protected] 5 points 1 year ago (3 children)

You running the latest Jerboa version?

If you can no longer see your subscribed communities in the sidebar, you could be on an older version that doesn't fully support v0.18.x

I really appreciate the transparency in this post. There's enough information for me to feel like I kind of know what's going on, and I can go dig into it deeper if I feel like it. This is a breath of fresh air from what I'm used to, thanks so much!

[–] [email protected] 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.

[–] [email protected] 6 points 1 year ago

Great work on moving away from the websockets

[–] [email protected] 6 points 1 year ago

was struggling for a while, but it seem to be nice and fast now.. thank you!

[–] [email protected] 6 points 1 year ago (3 children)

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

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

[–] [email protected] 6 points 1 year ago (2 children)

Dumb question: how can I set up a small ongoing donation to lemmy.world specifically? I can't seem to find it on the mobile site.

[–] [email protected] 6 points 1 year ago

the link is on the sidebar of the main page

Favicon seems to be missing now. Just a heads up! @[email protected]

[–] [email protected] 5 points 1 year ago (2 children)

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?

[–] [email protected] 6 points 1 year ago (1 children)

Resetting the password gets you in that one time the password was reset. Trying to login after that still doesn't work.

[–] [email protected] 5 points 1 year ago (2 children)

Login page is 404 erroring to me, at least the XmlHTTPRequest is that's associated with the button.

Profile pictures on user profiles are still stretched, and now the upvote arrows doesn't turn blue until you refresh the page when you press it

Other than that, this is a fantastic design update

[–] [email protected] 5 points 1 year ago* (last edited 1 year ago) (1 children)

When I sort my comments by β€œTop Week” I get stuff from 10 days ago.

Edit: Actually, no matter what time period I select, I still see old posts from 10 days ago.

Many thanks for the transparency! This is great.

[–] [email protected] 5 points 1 year ago (2 children)

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?
