Can a #Mastodon specialist enlighten me?

Yesterday my host, @mastohost sent me an email to tell me that my media storage was full (which surprised me, especially because I very recently started automatically deleting my oldest posts to avoid just this). Today, rummaging through the admin, I found this very surprising graph in #Sidekiq
What could this be? Or is it the deletion of old posts that triggered that spike in processes? But if old posts have been deleted, why is the media storage full?

A graph showing a spike in processes, whatever that means.

Well, the media is a combination of local posts and posts that federate with your server. So, even if you deleted all your posts, the media usage can still be high. Like, if you follow a few accounts that post a lot of media, that can require a lot of media storage while it is cached.

On Masto.host cached media is automatically deleted after 7 days - masto.host/re-mastodon-media-s…. You change it to a lower setting in the Content Retention Settings: masto.host/mastodon-content-re…

Thanks. And do you know what the spike in the graph could be?

Hard to say after the fact. Do you recall changing the Content Retention Settings around the 25th? That would be my first guess, given how long it had been running.

No, I didn't.
I merged another account into this one a couple of weeks ago, but that was... a couple of weeks ago, not then.
I remember the timeline not updating for a couple of hours at some point last week. Not sure if it's linked to this.

Hmmm.

Could you have deleted the old account around that date?

The other account is on Mastodon.social I just merged it into this one, but that was a week or two before.

Hard to say. A post being boosted by an account with a large following or interactions (back-and-forth public replies) with an account with a large following can cause something similar. But those are my best guesses.

Besides that, all I can think of is whether you had subscribed to Federation Relays or whether one of the accounts you followed had a lot of activity.

While a spike in Sidekiq jobs is happening, one can see what is being processed. After, it's hard to know what caused it.

I had one post that got boosted quite a bit, maybe there were some large accounts involved.

I mean, if it's not a big issue, it's not a big deal to know where it comes from. I'm more concerned about my media space being full. Will it go down once the cache is updated?

The chart shows it being back to normal. So not an issue.

Regarding media, you can wait a couple of days to see if goes back. If not you can lower your media retention settings.
