# 解绑磁盘

当您不再需要某个实例的额外存储时，可以解绑该磁盘，然后在需要时将其绑定到其他实例。解绑磁盘不会影响该磁盘上的数据。

<mark style="color:blue;">系统盘无法解绑。</mark>
{% endhint %}

## 前提条件

* 为防止数据丢失，请停止磁盘上所有文件系统的读写操作。
* 在解绑磁盘之前，请确保已卸载（Linux）或将其设置为离线状态（Windows）。否则，您可能无法将其重新绑定到其他实例。\
  **Linux**

  使用 `umount` 命令在 Linux 中卸载磁盘：

  ```bash
  sudo umount /dev/disk/by-id/xxxxxx
  ```

  **Windows**\
  \&#xNAN;**-** 按 **Win + X** 并选择 **磁盘管理**。\
  \- 找到您要解绑的磁盘，右键点击该磁盘，然后选择 **离线**。

## 操作步骤

1. 通过以下方式之一进入 **解绑磁盘**：
   * **实例详情** > **信息** > **存储** > **解绑**
   * **磁盘** > **操作** > **解绑**
2. 确保磁盘已卸载（Linux）或处于离线状态（Windows），如前几步所述，然后点击 **解绑**。
