Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.

Firstly move pict-rs to object storage. My instance's pict-rs uses 150GB alone. I pay less than $2/mo to put it on Cloudflare R2. Backblaze B2 might be even cheaper. Instructions: https://crates.io/crates/pict-rs#filesystem-to-object-storage-migration
If that doesn't help enough and you're comfortable with SQL, you can purge the unnecessary entries in
received-activities.Command:
delete from received_activity where published & NOW() - INTERVAL '3 days';(Lemmy has problems with ampersands so you'll have to edit it)Then do a
vacuum full received_activity;to reclaim the space.This deleted 98 million entries for me and reduced my database size from 49GB to 20GB a week ago when I started running out of space. No other effect as far as I can tell. Thanks @[email protected]
what is stored in
received_activity? anything important? I mean obviously it's something the instance has received from other instances but is this then stored somewhere else (like comments then stored elsewhere for eg)As far as I've been told it's basically just a log of all received activities. Nothing references it.
Nothing seems to have gone wrong in the past week on thelemmy.club since I removed it. I do have backups though.
Nice, thank you.
