Minio doesn't make any sense to me in a homelab. Unless I'm reading it wrong it sounds like a giant pain to add more capacity while it is already in use. There's basically no situation where I'm more likely to add capacity over time than a homelab.
You get a new nas (minio server pool) and you plug it into your home lab (site replication) and now it's part of the distributed minio storage layer (k8s are happy). How is that hard? It's the same basic thing for Ceph or any distributed JBOD mass storage engine. Minio has some funkiness with how you add more storage but it's totally capable of doing it while in use. Everything is atomic.
