Hi, I’m new with self-hosting but managed to set up my own Lemmy and Mastodon instances on a VPS recently. However, I ran into an issue with disk space quite rapidly (which I had way too few, because I started with the cheapest, smallest package for my VPS).
Now I prepare a new setup, where I’ll be able to dynamically scale disk space as needed, but this can get expensive quickly. Therefor my question: How much disk space do I typically need for private (1-3 user) instances of Lemmy and Mastodon? Are there settings, where I can limit the disk space utilization (at the cost of older stored content being overwritten)?
I would be fine with needing up to like 30-40 GB, but any more than that would be getting kinda expensive …
I have my lemmy instance currently using about 2 GB space, I’m going to set up Mastadon this weekend I hope. There are cheap smaller dedicated servers from kimsufi for like $10 with 1/2 TB HDD.
Also Hetzner cloud has compute and disk separated, so you can scale one or the other.
I’ve got a 500GBSSD box from Hetzner, but I’m also hosting other things there and dropped VMs from Linode I had previously and consolidated there.
You could use object storage, like s3 or wasabi, for lemmy picture/media storage, if that’s eating up most space. “cloud” providers are bit bananas when you need more disk, at one point its cheaper to go down a dedicated route. Depends on your budget…
Edit: Others might chime in with a better answer, at the moment bot sure what your budget is, so its bit of assumptions from my side.
With Lemmy, it will depend more on the amount of media that your users upload than anything. With Mastodon, you also will have to consider the amount of data in the cache.
With Mastodon, I have (small) instances running for about an year or so which are using less than 100GB, and I have instances from power users that went on to take ~250GB in less than a month.
You can set up Mastodon to delete posts after a certain age and to clear the remote cache periodically. This would help mitigate both things.
No expert here but usualy you use an external object storage (should be configurable in lemmy via pict-rs) which should be cheaper then VPS storage ^^
Maybe have a look into it.
That will depend on usage. If you subscribe to a lot of communities that are very active the database will grow fairly fast. If your users post a ton of large files then that will grow much much faster than the database. Your instance also caches image thumbnails so that can grow somewhat fast too.
Currently sitting at 750 MB for pictrs and 500MB for postgres after a week, so you may want to plan a decent size but 30-40GB should be fine for a while to get started. Add some monitoring for when it reaches 10, 20 and 30GB and keep an eye on it.
Heya, sorry for the necropost, but would you mind sharing how you’re doing on storage these days? I’m looking at spinning up a Lemmy instance of my own and I’m curious about the storage aspect on small instances
Will there be some sort of OS running on this VPS like Ubuntu, Debian etc.? The folder my Lemmy instance is stored in is 117 MB big. I have 1 user and follow 23 communities.
