- Each pool expects each host in this pool has the same number of drives specified as any other host.
- Mixing `local-path` and `distributed-path` is not allowed, doing so would cause MinIO to refuse starting the server.
- Ellipses notation (e.g. `{1...10}`) or bracket notations are fully allowed (e.g. `{a,c,f}`) to have multiple entries in one line.
