Comments and improvement suggestions welcomed!

Anything to improve is good! I have been running this script with days 5. All of this may update frequently, so check back.

This script is adapted from Hosting your own Mastodon server.

I am currently running a 2 server cluster. The main server is Mastodon v4.1.6 on Ubuntu 20.04 LTS and the database server is PostgreSQL on Ubuntu 22.04 LTS. With ~25 users, disk space used averages around 50GB or less on the main server, and around 10GB or less on the database server.

This script is installed in /home/mastodon/maint/ on the main server. There is no configuration of the database server necessary for this script, nor any functional difference between an all in one Mastodon server and Mastodon with a separate database server.

# This does the heavy lifting and removes locally cached copies of

# By default it's set to delete media older than 7 days
# Adjust days with --days, eg --days 3 for a more aggressive setting.

# Remove local thumbnails for preview cards (the thumbnail when links are shared, etc)

# Deletes remote accounts that never interacted with local accounts
# Removes many avatar and header images as part of this

# Removes files that do not belong to existing media attachments
# For example if you attached a file to a post composer but never posted it
# This command and the one after it are slow to run, so I like to keep them for last
RAILS_ENV=production /home/mastodon/live/bin/tootctl media remove-orphans

# Remove unreferenced statuses from the database, such as statuses that
# came from relays or from users who are no longer followed by any local accounts,
# and have not been replied to or otherwise interacted with (90 days default)
RAILS_ENV=production /home/mastodon/live/bin/tootctl statuses remove --days 90

*** Note it appears tootctl media remove is going to have an update to flags, re: Issue 23628

Thanks!
