Garbage Collection
Some various commands to clear cached data and free up storage:
tootctl media remove –days N Removes cached media. Default 7 days.
tootctl media remove –prune-profiles Remove cached avatars and headers.
tootctl media remove –remove-headers Remove cached headers
tootctl accounts prune Prune remote accounts that have never interacted with a local user
tootctl statuses remove Remove stale statuses from remote users
tootctl preview_cards remove Remove link previews
tootctl media remove-orphans Remove media not linked to any posts
Slow Startup
Docker/Podman instances can be very slow to start up. This seems to be possibly linked to the overlay2 driver and the entrypoint trying to chown contents in the public folder. More investigation needed.
Backups
An example of how to backup a containerized instance.
podman exec ${DB_CONTAINER} pg_dumpall -U mastodon | gzip > /temp/mastodon/postgres.sql.gz Dump the database to a file
tar -czf /temp/mastodon/accounts.tar.gz ${VOLUME}/pubsys/accounts Backup media attachments
tar -czf /temp/mastodon/${CURDATE}.tar.gz /temp/mastodon/* Compress everything to a file
