I’ve self hosted Mastodon twice in the past and both times, it took some real effort to keep the instance afloat.
The first time, the instance kept using up data until the hard drive filled up. Just for at most 4 users. I didn’t know it kept the files on the local server and it filled up everything quick.
The second time, the cloud instance worked itself in a routine update.
Is there any fedi software that works best as a single user instance? Something low power but can still communicate and subscribe to mastodon accounts?
You need to set the cache time for remote media in masto. That way it clears after X days
If you didn’t do that, it will just fill up, yes
Currently at about 120GB media cache for 3 days on instances that are relayed over big relay networks
