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 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

    • Clearing cache didn’t work for me.
    • Different web browser didn’t work for me
    • Resetting did work for Lemmy on desktop

    but can’t log into any app at this point.

    We’ll see what happens in a bit.

    Edit: slowly opening up I think.

    Edit 2: I can now get into all of the big 3 (Connect, Wefwef, Jerboa).

      Out of curiosity, was the reset password link in French? Also, which apps are you using? I finally was able to get into wefwef, and hadn’t really tried another app up to this point.

        Password reset was not in french. (I’m in US and reset email and the actual page was in English).

        I’m using the Big Three. (Connect = Working, Wefwef = Working, Jerboa = not working)
