如果您想要将新格式化的分区挂载到现有的`/www`目录，同时保留`/www`目录中的文件，您需要先将`/www`目录中的文件移动到安全的位置，然后挂载新分区，最后将文件移回挂载点。以下是详细步骤： 1. **备份`/www`目录中的文件**： 在挂载新分区之前，您需要将`/www`目录中的所有文件移动到一个临时位置，以防止它们在挂载过程中被覆盖。例如，您可以将文件移动到`/tmp/www_backup`： ```bash sudo mkdir /tmp/www_backup sudo mv /www/* /tmp/www_backup/ ``` 2. **挂载新分区**： 假设您的新分区是`/dev/sda1`，并且已经格式化为ext4文件系统，您可以使用以下命令将其挂载到`/www`： ```bash sudo mount /dev/sda /www ``` 3. **将文件移回`/www`**： 挂载新分区后，您可以将之前备份的文件移回`/www`： ```bash sudo mv /tmp/www_backup/* /www/ sudo rmdir /tmp/www_backup ``` 4. **设置自动挂载**（可选）： 如果您希望在系统启动时自动挂载这个分区，您需要编辑`/etc/fstab`文件。在编辑之前，请确保您了解每个字段的含义，并且正确地指定了设备和挂载点。以下是一个示例条目： ```bash /dev/sda1 /www ext4 defaults 0 0 ``` 在编辑`/etc/fstab`之后，您可以使用`mount -a`命令来测试配置是否正确，而不会重启系统： ```bash sudo mount -a ``` 如果没有错误消息，说明配置正确。 请注意，这些操作需要root权限，因此请确保您使用`sudo`来执行这些命令。此外，在执行任何操作之前，请确保您已经备份了所有重要数据，以防止意外数据丢失。 通过finalshell观察到挂载已成功  Loading... 安装好后打开树莓派 执行`fdisk

虽然但是，为什么没有好的脚本自动挂，大家都是fstab。感觉Linux还是残留太多弱智东西（不是Linux本身而是上下游的所有人）
