Now that I have my Minio => SeaweedFS migration for my Mastodon instance metalhead.club under control, I have written a few words about it in my blog.

Perhaps this will be helpful for other administrators who are looking for something new because the Minio S3 server is no longer being maintained.
I pay particular attention to the difficulties I encountered due to the large number of files (which caused problems).
So far, SeaweedFS S3 has been working wonderfully for me!
My thanks go to
@stefanoStefano Marinelli, whose blog entry inspired me to use SeaweedFS:
