你的命令行报错“vllm: error: unrecognized arguments”，说明 vllm serve 命令后面有不被识别的参数，或命令格式有误。请检查命令是否有多余或格式错误的参数，确保 serve 后只跟模型路径和合法参数，例如：

```bash
vllm serve /mnt/afs/share_models/git_models/Qwen/Qwen3-32B --port 6366 --tensor-parallel-size 8

```

如仍有问题，建议用 `vllm serve --help` 查看所有支持的参数和用法，确保没有拼写或格式错误。详细参数说明可参考[vLLM CLI官方文档](https://github.com/vllm-project/vllm/blob/main/docs/cli/README.md)。

需要更详细的排查步骤吗？
