@dkdndes I haven't actually used SeaweedFS in a while and I don't have a Swarm cluster to test on at the moment. You are probably best trying out @xirius's YAML.

@xirius, in order to scale the filer you have to setup an external filer store, such as Cassandra or a plethora of other databases. Then you can scale to any number of filers as long as they all point at the same filer store. Of course that means that now you have to take into account how you are going to scale the chosen filer store as well.

@zicklag oh I see, thanks. I assumed filer should replicate the metadata for redundancy.
