If a single disk has multiple targets, does it mean there is only one engine corresponding to multiple targets? That is, targets are only logical, and in reality, all targets on a single disk form a storage pool, right?

For the Rust version of the chunk engine, yes. The purpose of doing this is to allow all targets to share the same disk space, enabling a simpler chunk recycling strategy (only marking without actual deletion).

对于 Rust 版本的块引擎，是的。这样做的目的是允许所有目标共享相同的磁盘空间，从而实现更简单的块回收策略（仅标记而不实际删除）。
