- 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 and bracket notation (e.g. `{1...10}`) are allowed.

### Headings

- Follow the existing Japanese style: short, descriptive headings (often noun phrases), e.g. 「チェック」.
- Do not add a trailing period at the end of headings.

### Quotes

- Prefer Japanese corner brackets 「」 in normal prose when quoting a term.
- Do not change quotes inside inline code, code blocks, URLs, or file paths.

### Ellipsis

- Keep ellipsis style consistent with existing Japanese docs (commonly `...`).
