One filesystem for cluster

[alpharde]

Hi, I want to create a single filesystem for docker volumes that spans four nodes.
I already did the replica configuration in keydb for all of these, this is what i'm missing:

• How to set bucket replication in minio
• Could not figure out some values for the docker plugin in swarm (metadata url, metadata password)

Also, I'm curious if juicefs handles concurrency in these cases and how.
