Help: federation issues with posts, users, and comments not showing up
I recently migrated from lemmy.ml to lemmy.world to help with decentralizing and server load. I've noticed that a community I moderate, c/[email protected], is not updating: one of the mods I added isn't showing up on the sidebar, and a mod I removed is showing up. Plus, if I visit my community from lemmy.ml instead of lemmy.world, I see posts that aren't showing up on lemmy.world.
This is still ongoing today (as of the time of this comment).
I created a comment on lemmy.ml to a posting on lemmy.world and it never made it to lemmy.world or another instance I have subscribed to the community. It has been over an hour:
I'm having trouble with this too. I mod [email protected] from both here and lemmy.world.
I can't even see the community here directly anymore!
But using the federated URL to itself works
Comments are also not federating fully. From here this post, created from lemmy.one, has 6 comments
But from lemmy.world it has 5
And this post https://lemmy.ml/post/1226483 viewed directly from lemmy.ml shows 13 comments, but I can only see 9. For both the community settings and my own user settings I have all languages selected, so it shouldn't be a language filter problem.
Yeah, totally understandable to have growing pains. I just wanted to make sure I that I get the issues I'm seeing reported. They can't fix an issue they don't know about.
I think people moving to smaller servers is actually adding a different type of overload, as federation is falling over when there are over 100 peers... the more popular a topic, the more peers have subscribers and that creates a big federation replication load.
As far as i can tell, there is no protocol for server integrity checks to find missing replication of comments/posts, nor is there a backfill protocol or logic to repair replication.
Is there a workaround for this?
First, you have to have a active subscribers on both servers you are looking at, and then from that time forward they are supposed to federate content.
I have tried adding new new nested comments, edits to my own postings and comments to try and "workaround" the problems, but it isn't always an option and I haven't found a reliable way to get servers to heal their copies of missing content.
